Abstract

PURPOSE: To provide an information processor and an output method which can output various analysis results through a simple operation. CONSTITUTION: The polygons showing the surface or the section of a model to be analyzed are extracted, and a drawing flag showing the drawing that is used to plot the analysis result of the model against every extracted polygon (S11, S12). Then the analysis result is plotted to every polygon by means of the drawing (such as the contour line display, the arrow display, the boundary line display, etc.) which are designated by the drawing flags of every polygon stored in a storage means (S14 to S22). In such a way, the drawing can be individually decided for every polygon and therefore various analysis results are obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus and an output method for displaying analysis results such as a finite element method, a boundary element method and a difference method. Particularly, the present invention relates to an information processing apparatus and an output method suitable for expressing a result by displaying contour lines, arrows, etc. on an analysis model.

[0002]

2. Description of the Related Art In recent years, along with the development of computer performance, numerical experiments centering on the finite element method and the difference method have been widely carried out as one means for designing, and their importance is increasing year by year. In such a numerical experiment, a model in which the model is divided into fine elements (element division model) is used.

When displaying the results of analysis using such an element division model, a diagram in which contour lines or arrows are drawn on the surface or cross section of the analysis model is often used. That is, a contour line is drawn based on the scalar value as the analysis result, or a diagram in which the vector amount is displayed by an arrow is used.

FIG. 16 is a view for explaining a general analysis result display option. In addition, FIG. 17 is a flowchart for explaining a general analysis result display procedure. FIG.
In this example, as shown in FIG.
The model surface and cross section are displayed as the display portion, and the display and non-display of the boundary line of the element can be selected as an option. In addition, here, a means for displaying the analysis result on the graphic display 11 so as to visually appeal is called a drawing method, and a portion for displaying in the model using the drawing method is called a display portion.

The individual steps will be described below with reference to FIG. Here, it is assumed that the analysis result to be displayed and the display portion (surface and cross section) have already been set.

First, a polygon (polygonal surface) for displaying is extracted from the analysis model (step S50).
1). That is, a polygon described below is extracted for a portion (collection of elements; hereinafter referred to as an element block) designated by the user and displaying an analysis result.

Polygons will be described with reference to FIGS. 18 and 19. FIG. 18 is a diagram illustrating a polygon representing a surface in a divided model composed of two hexahedral elements designated by the user as a display target. FIG. 19 is a diagram for explaining a polygon representing a cross section in a divided model composed of two hexahedral elements designated by the user as a display target.

Reference numeral 81 represents a hexahedral element. In FIG. 18, reference numeral 82 is a polygon representing the surface of the element block 81. The polygon representing the surface is extracted as a surface (generally referred to as a free face) that is not shared by a plurality of elements among the surfaces of each element of the element block. On the other hand, FIG.
In the figure, reference numeral 83 designates the element block 81 as P1, P2 in the drawing.
Two polygons representing a cross section when cut at a plane including three points P3. In this way, the cut surface of each element becomes a polygon representing a cross section.

Here, when displaying the analysis result on the surface of the model, the surface of the element block (free face)
When displaying the analysis result on the cross section, a polygon representing the cut surface of the element is extracted.

Next, the subsequent processing is divided according to the drawing method (step S502). In the case of contour lines, the process proceeds to step S503, and the polygons are processed one by one by the loop following the process and displayed on the display.

First, in step S504, contour lines are displayed on the polygon surface based on the analysis result. And
In step S505, it is determined whether the display of the element boundary line is designated as an option. If specified, the boundary line of the polygon (the boundary line between the inside and outside of the polygon) is drawn (S506). The above steps S504 to S506 are performed on all the polygons extracted in step S501 (step S50).
7).

On the other hand, when the drawing method is an arrow in step S502, the process proceeds to step S508, and in the loop following this, an arrow is drawn for each polygon and displayed on the display (step S50).
8). That is, in step S509, when the arrow is displayed in the polygon surface based on the analysis result and the display of the element boundary line is designated as an option, the boundary line of the polygon (the boundary between the inside and the outside of the polygon is A line is drawn (steps S510 and S511). Step S509-
The processing of S511 is performed on all the polygons extracted in step S501 (S512). Through the above processing, a diagram displaying the analysis result desired by the user can be obtained.

As shown in FIG.
The display process of the division model as shown in will be described below.
FIG. 4 is a model of a two-dimensional magnetic field analysis, 20 indicates an analysis region, region 21 is air, and regions 22 and 23 are magnetic substances. Here, for convenience, the respective portions of the regions 21 to 23 will be referred to as regions R1 to R3, respectively. Although not shown in the figure, the regions R1 to R3 are assumed to be divided by fine elements.

In the present model, the case where the analysis result is designated to be displayed as contour lines on the magnetic material portion will be described (in the case of the two-dimensional model as in this example, there is no cross section). In addition, the boundary line of an element shall also be displayed here.

(1) First, the surface of the element of the magnetic material portion is extracted. In the case of a two-dimensional model, since the elements themselves are the element surface, the elements in the regions R2 and R3 are extracted as polygons. (2) Since contour lines are displayed, the processing from step S503 is performed on each extracted polygon. (3) Draw contour lines inside the polygon based on the analysis results. (4) Display the boundary line of the polygon. The boundary line of this polygon becomes the boundary line of the element. (5) The processes of (3) and (4) are repeated for all the polygons extracted in (1).

By the above-mentioned processing, the desired analysis result diagram is obtained. In this example, the contour lines are displayed on the magnetic material portion, but the analysis result can be displayed by the same procedure when displaying in other regions or when displaying arrows.

By the way, when displaying the results using the above-mentioned various projection methods, it is necessary to set some parameters (herein referred to as drawing parameters) in advance before drawing. As the drawing parameters, for example, (1) type: 2 "drawing only lines representing contour lines" and "painting between contour lines with a predetermined color for each level"
Select one of the streets. (2) Number of contour lines: Specify how many contour lines to display (3) Value of each level: Specify the level (height) value of each contour line, and specify , And set them at equal intervals) "or" arbitrary setting (specify level values individually for each contour line) ". (4) Contour line color: By specifying the color to display each contour line,
Specified by either "automatic (automatically set appropriate color)" or "arbitrary setting (color is specified individually for each contour line)". Is mentioned.

Although the parameters relating to contour lines are called drawing parameters here, generally, the drawing method (contour lines, arrows, etc.) itself can be considered as drawing parameters.

In general, the analysis result is displayed by several expression methods by changing these drawing parameters and examined from various angles. Then, when there are a plurality of similar analysis results, it is often the case that all the results are displayed in some similar expressions and the results are compared and examined.

In order to create a diagram in which all the results are displayed in some similar expressions, the same operation is repeated for each result. Therefore, in order to eliminate such annoyance, the contents of the operation are programmed (the file containing the program is called a restart file), and the drawing parameters can be automatically changed one after another and displayed. There is.

Generally, the display device has two modes, that is, a mode for creating a restart file and a mode for not creating a restart file. The restart file is created only in the create mode. In the restart file creation mode, the operations performed by the analyst are written out to the external memory one by one, and this process is repeated until the creation of the restart file is completed. The file thus created becomes the restart file. In addition, the commands recorded in the created restart file are sequentially executed in the recorded order.

A general automatic display procedure using the upper restart file will be described with reference to FIGS. 20 and 21. FIG.
0 is a diagram illustrating an example of the data structure of a general restart file. In addition, FIG. 21 is a flowchart showing a general procedure for displaying an analysis result using a restart file.

When automatically displaying the analysis result, the analyst first creates a restart file. That is, one of the analysis results is used to display all the results in a desired expression method, and all the operations are recorded as a restart file. Next, replace the analysis result with the one you want to display automatically,
Execute the created restart file.

An example of actually creating a restart file will be described by taking an example of automatic display as in FIGS. Z1 to Z4 as shown in FIG. FIG. 13 shows the setting of the drawing parameters of the drawing to be displayed, all the displayed figures are contour maps, and the four figures Z1 to Z4 shown in the figure number column are drawn sequentially. In order to simplify the description, the drawing parameters are three (the above-mentioned), that is, the type, the number of contour lines, and the value of each level (contour line interval). The drawing parameter settings for each figure are as shown in the table. For example, in the drawing of FIG. Z1, the contour map is displayed with the type as A1, the number as B1, and the level value as C1. In addition, the set value surrounded by a circle in the figure indicates that the analyst needs to perform the operation of setting the parameter.
That is, for the part not circled, the value has already been set in the display process up to the previous time, and therefore the analyst does not need to set the value again.

In the restart file creation mode, the analyst automatically creates a restart file by performing the following operation on the display device.

(1) Type is set to A1, (2) Number is set to B1, (3) Level value is set to C1, (4) Drawing is performed (Z1 drawing), (5) Type is set to A2, (6) Drawing is performed (Z2 drawing), (7) Number is set to B2, (8) Drawing is performed (Z3 drawing), (9) Type is set to A1 ,
(10) Draw (draw Z4).

When the process of the above operation is stored as a restart file, it becomes as shown in FIG. In FIG. 20, the restart file F91 is created on the external memory and has the contents of C86 to C95. In addition, here C8
The contents of 6 to C95 correspond to the respective operations (commands) of (1) to (10) above, and are actually described using a predetermined code.

Next, the process of executing the restart file F91 will be described with reference to the flowchart of FIG. When the analyst exchanges the analysis result with one that he / she wants to automatically display and executes the restart file F91, the sequential instructions are executed as follows.

(1) First, the C86 instruction is read (step S601). From the instruction content, it is determined that the data is changed (step S602), and the type parameter is changed to A1 among the drawing parameters used by the apparatus for actual display (step S603).

(2) Similarly for C87 and C88,
After reading the instruction (step S601), it is determined that the data is changed based on the content of the instruction (step S602).
The corresponding parameter of the drawing parameters used by the device for display is changed (step S603).

(3) Next, when the command of C89 is read (step S601), it is judged from the contents of the command that it is a drawing command (S602), and the analysis result is drawn (Z1 is displayed) (S604). ). Similar processing is performed for C90 to C95.

(4) Finally, restart file F91
When the execution of all the instructions stored in is completed, this processing ends (step S605).

In the above description, the restart file is created through the actual operation of the analyst. However, in general, the restart file may be directly described using a text editor. That is, for example, in the example of performing the display of FIG. 13, the restart file F91 of FIG.
There is also something like creating directly with a text editor.

[0034]

However, in the above-mentioned embodiment, since the result can be displayed only by the monotonous method, there are the following problems.

(1) Only one projection method can be used for one drawing. For this reason, if you wanted to examine the results using several projections, you had to prepare as many drawings as there were projections. For example, in the model shown in FIG. 4, even when it is desired to see the result with the arrows in the region R1 and the contours in the regions R2 and R3, the result is displayed in two times: a diagram with only the arrow and a diagram with only the contour line. I had to do it. As a result, it takes a lot of time to display, and when a copy of the displayed figure is made on paper, the paper is wasted. Further, since the obtained result spans two figures, it may be difficult to interpret the result.

(2) Only one type of analysis result can be displayed for one drawing. Therefore, when I wanted to see some results, I had to prepare as many figures as the results. For example, in the model shown in FIG. 4, when looking at the results of the magnetic field strength in the region R1 and the results of the magnetic flux density in the regions R2 and R3, a diagram showing only the magnetic field intensity and a diagram showing only the magnetic flux density, The results had to be displayed twice. As a result, the same problem as in the above item 1 occurred.

(3) In many cases, it was difficult to understand the positional relationship of the elements displaying the results in the entire analysis model. For example, in the model shown in FIG. 4, when the results of only the magnetic material portion are displayed, the positional relationship cannot be understood because there is no representation of the analysis region. This problem occurs especially when the result is displayed on the cross section. That is, it was confusing because the section was not displayed just by displaying the section.

Various solutions have been studied and implemented up to now for the above-mentioned problem, but the operation method is complicated and it is very difficult to use, and the functions are limited (for example, the above). Problems such as (1) of the problem point were solved) occurred, and none of them completely overcome these problems.

Further, the method of continuously displaying the analysis results using the restart file has some difficulties when a part of the result display is changed. This will be described below.

First, as a basic matter, there were the following problems. That is, (1) An environment where a text editor can be used is required: If the text editor cannot be used, the restart file cannot be changed, so the display could not be changed. (2) Knowledge of code system corresponding to operation is required:
Generally, in the restart file, all operations (commands) performed by the analyst are described in code. Therefore, it could not be changed without knowledge of the code system.

Next, due to the characteristics of the restart file,
There were the following problems. That is, (3) it is difficult to search for a changed part: Generally, the restart file is very large, and it takes a lot of time and effort to find the corresponding part. In particular, when a restart file is actually created through an operation as described above,
This includes operations at the trial and error stage and mistakes made by carelessness. As a result, the restart file was very verbose and difficult to understand, and it took more time and effort to search for the relevant part.

(4) The change of data for the corresponding part is
This may affect subsequent instructions: This will be explained by taking as an example the case where the level value of the drawing number Z3 in FIG. 13 is changed to C2 and automatically displayed.

In this case, the restart file F in FIG.
Immediately before the C93 command (drawing Z3) of 91, the command for setting the level value to C2 is inserted. However, with such a change alone, the level value will be C2 even in the subsequent Z4 drawing. Therefore, in order to avoid this, it is necessary to insert an instruction for restoring the setting of the level value immediately after the instruction of C93. However, in order to know what is set as the level value in Z3 (C93), it is necessary to search back to the point before the drawing of Z1 (C88).

As described above, even when one drawing parameter is changed, in order to prevent the subsequent processing from being affected, it is necessary to investigate the program over a wide range.
It took a lot of time and effort to do so. In particular, here is a very simple example, but since the actual restart file is more complicated, this change work is very difficult, and the subsequent display may be erroneously displayed due to a mistake in the change. there were.

Various solutions to the problems mentioned above have been studied and implemented so far. For example, annotations were added to the restart file to make it easier to read, and the statement expression (code system described above) was devised. However, as mentioned above, restart files tended to be verbose, and we couldn't completely overcome these problems.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object thereof is to provide an information processing apparatus and an output method capable of outputting various analysis results by a simple operation.

Another object of the present invention is to make it possible to display the results in a plurality of projections on one drawing.

Another object of the present invention is to be able to display a plurality of types of analysis results in one figure.

Another object of the present invention is to make it possible to draw a diagram in which the position of the portion displaying the analysis result in the entire analysis region is clearly shown.

It is another object of the present invention to provide an information processing apparatus and an output method that allow an analyst to easily automatically display the analysis result and easily change the content of the automatic display.

[0051]

That is, an information processing apparatus that outputs the analysis result of the model by drawing the analysis result on a polygon that represents the surface or cross section of the analysis target model, and is a drawing method used for drawing the analysis result for each of the polygons. And a drawing means for drawing the analysis result for each of the polygons using a drawing method specified by the drawing method information stored in the storage means.

Preferably, the projection information can specify a plurality of types of projections at the same time, and the drawing means uses the specified projections when the projection information specifies a plurality of projections. The analysis result is drawn on each of the polygons. This is because the analysis result can be drawn on one polygon (region) by a plurality of types of drawing methods, and a drawing that is easier for the user to analyze can be provided.

Further, it is preferable that the apparatus further comprises designation means for individually designating a display projection for each element to be displayed, and the storage means is designated by the designation means for polygons included in each of the elements. The projection information indicating the display projection is stored. Generally, it is sufficient to change the projection method for each element (region). Therefore, since the display projection can be designated for each element, the display of the projection can be efficiently performed.

Further, preferably, the designation means includes means for displaying a list of elements to be displayed for each display projection. This is because the operability when designating a drawing method is improved.

Further, preferably, the drawing means further comprises holding means for holding correspondence information for associating each drawing method with an analysis result to be drawn, and the drawing means stores drawing method information stored in the storage means in each of the polygons. By using the drawing method designated by, the analysis result associated with the drawing method is drawn by the correspondence information. This is because the analysis result to be drawn can be changed according to the drawing method, and a wider variety of drawing can be performed.

Further, preferably, a setting means for setting the correspondence information is further provided. This is because the drawing method and the analysis result can be associated with each other as desired.

Preferably, the drawing means further comprises a holding means for holding allocation information to which an analysis result to be drawn is assigned for each polygon, and the drawing means stores drawing information for each polygon in the storage means. The analysis result assigned to the polygon by the assignment information is drawn using the drawing method designated by.

The designated analysis result is assigned and held as assignment information. A desired analysis result can be assigned to a desired area.

Further, preferably, the drawing method includes drawing a boundary line of an element to be displayed. Alternatively, the projection is
Includes drawing of the outline of the element to be displayed. Since the boundary line or contour line of an element can be designated as one of the drawing methods, it is possible to specify whether or not the boundary line or contour line is drawn for a desired element (region), and operability is improved.

Further, preferably, in the case where the drawing of a plurality of projections designated on the same polygon causes a problem in the display of the analysis result, drawing by any one of the plurality of designated projections is performed. It further comprises a prohibition means for prohibiting. It is possible to prevent the analysis results from becoming difficult to see by drawing with multiple projections.

An information processing apparatus having another configuration of the present invention that achieves the above object is an information processing apparatus that sequentially draws a plurality of drawings for drawing analysis results and the like.

[0065]

According to the above arrangement, the storage means stores drawing method information indicating a drawing method used for drawing the analysis result for each polygon representing the surface or cross section of the analysis target model. Then, the drawing means for drawing the analysis result draws the analysis result for each polygon by using the drawing method specified by the drawing method information of each polygon stored in the storage means. Since the drawing method can be individually determined for each polygon, various analysis result outputs can be obtained.

Since the drawing information is completed for each figure, when editing the drawing information, it is sufficient to perform the editing process on the desired drawing information.
Operability is improved.

[0067]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

<Embodiment 1> FIG. 1 is a block diagram showing the configuration of a computer of this embodiment for displaying analysis results. In the figure, reference numeral 11 denotes a graphic display (hereinafter referred to as a display), which displays various processing results and the like. 12 is a central processing unit (hereinafter referred to as CPU)
That is, various controls are realized by the control program stored in the memory 73. 13 is a memory, ROM
And RAM. A control program executed by the CPU 12 is stored in the ROM. Also, R
The AM provides a work area required when the CPU 12 executes various processes. An external memory 14 is composed of a magnetic storage device or the like and stores data in the form of a file. The control program executed by the CPU 12 may be stored in the external memory 14, loaded into the RAM in the memory 13, and executed. An input unit 15 is used by the operator to input various instructions.

With the above configuration, when the user inputs (or specifies) the data of the figure to be displayed through the input unit 15, C
After performing the required calculations in PU12, display 1
A diagram of the analysis result is displayed in 1.

FIG. 2 is a diagram for explaining the display attributes of the elements for displaying the results in this embodiment. The display method is shown in Figure 2.
As shown in, there are three types of display, element display, contour line display, and arrow display. Here, the element display is to display the polygon of the corresponding element block with a boundary line and to fill it with a single color, and simply indicate the shape of the element. Therefore, although the element display is not a method of displaying the result, as described later, by positioning the element display in this way, the result display processing can be rationally performed and the display can be easily set. On the other hand, the display portion includes the model surface and the cross section as described in the conventional example.

As shown in FIG. 2, there are six combinations of display method and display portion in this example, A1 to B3. Then, in this embodiment, display elements are individually set for each of A1 to B3. Then, each polygon is displayed according to the set information. A1 to B
As shown in FIG. 3, in the present embodiment, the operator sets the display target by the element, but in the program, the polygon is extracted from the element for management. That is, information about what drawing method is used to draw each polygon is managed. The display attributes A1 to B3 as shown in FIG. 2 are first set for each element block, and the set contents are stored in the memory 13. Then, it is referred to when setting the projection information for each polygon.

FIG. 3 is a flow chart showing the procedure of the analysis result display process in the first embodiment. The control program that implements this procedure may be stored in the ROM of the memory 13 or may be configured to be loaded from the external memory 14 to the RAM of the memory 13 as necessary.

(1) A polygon designated by any of A1 to B3 is extracted from the analysis model (step S1).
1). First, a polygon that represents the surface of an element block including elements specified by any one or more of A1 to A3 is extracted. Similarly for B1 to B3,
For elements specified by any one or more of ~ B3,
A polygon representing the cross section is extracted.

(2) For each of the extracted polygons, a flag indicating which drawing method is used to display is set (step S
12). For example, three flags F for each polygon
(1), F (2), and F (3) are prepared, and F (1) is designated when the element display is designated, and F (2) is designated when the contour display is designated. When the display is designated, the flag of F (3) is set to ON. Note that, for convenience, this process is an independent process after step S11, but in practice, it is efficient to perform this process at the stage of extracting each polygon in step S11.

(3) By the subsequent loop, the results are sequentially drawn on the polygons extracted above (step S13). In the loop, the flag of polygon i is set to F.
It is represented by i.

(4) The state of the contour line flag F (2) is checked (step S14). If F (2) is ON, contour lines representing the result are drawn inside the polygon (step S15). On the other hand, when F (2) is OFF, the element display flag F (1) is checked (step S16),
If (1) is ON, the inside of the polygon is painted (step S17).

(5) The state of the flag F (3) indicated by the arrow is checked (step S18). If F (3) is ON,
An arrow representing the result is drawn at the center of the polygon (step S19). In step S18, the flag F (3) is set to O.
If it is FF, the process directly proceeds to step S20.

(6) Check the element display flag F (1) (step S20). If F (1) is ON, the boundary line of the polygon is drawn (step S21). If F (1) is OFF in step S20, the process directly proceeds to step S22.

(7) The above processes (4) to (6) are performed on all the polygons extracted in (1) (step S22). This gives a view with the following displayed for each element block: That is, A1: surface of element block (fill) and element boundary line A2: contour line on surface of element block A3: arrow on surface of element block B1: cross section (fill) and element boundary line B2: contour line on cross section B3: cross section Arrows In addition, for elements (polygons) for which a plurality of display projections have been set, display by all the projections is performed. However, by the processing of steps S14 to S17, the elements for which the element display and the contour line display are designated at the same time are not filled, and the contour lines with the element boundary lines are displayed. This is because the filling process is performed after the contour line drawing. Therefore, the arrow display can be displayed on the surface on which the fill is drawn. If the contour line is drawn after the filling, the filling and the contour line display can coexist.

As can be seen from the above description, the first embodiment
According to this, it becomes possible to individually give an element to be applied and displayed for each display projection. That is, the element shape display (including the boundary line) is displayed for the element set in the element display, the contour display is displayed for the element set in the contour display, and the element display is displayed for the element set in the arrow display. The arrows are displayed so that they do not interfere with each other except the display of the surface of the element display and the contour display, and they are completely independent.

For the elements designated only by A1 and B1, the element block shape and the element shape in the cross section are displayed, so that not only the result display but also the drawing of the element division diagram is performed. You can see that it can be put in the figure of the result display.

The above will be described more specifically using the model of FIG.

FIG. 4 is a diagram showing an example of a two-dimensional magnetic field analysis model. In the figure, 20 indicates an analysis region, region 21 is air, and regions 22 and 23 are magnetic substances. Here, for the sake of convenience, the respective portions of the regions 21 to 23 are respectively referred to as regions R1 to R3.
I will call it. Although not shown in the figure, the region R
It is assumed that 1 to R3 are divided by fine elements. In this model, the procedure for individually setting the drawing method in each area and displaying the analysis result will be described below (in the case of the two-dimensional model as in this example, there is no cross section).

FIG. 5 is a diagram showing a display data setting screen for making display settings of the model shown in FIG. In the figure,
Reference numeral 30 is a window showing a setting screen, and reference numeral 31 is a label (comment) showing the contents of the switch. 32,
33, 34, 35, 36, 37 are the elements shown in FIG.
1, A2, A3, B1, B2, B3 is a switch for setting which projection method (display attribute) is to be set, and elements belonging to regions R1 to R3 can be independently selected (at the same time). You can select more than one). Note that such an operation screen can be created by using a window system such as X Window or Windows (both are registered trademarks).

Using this setting screen, the drawing method for displaying the results is set for each of the regions R1 to R3 in the model of FIG. Here, the switches R32 to R34 are set as shown in FIG. 5 in order to display the region R1 by an arrow, the region R2 by a contour line with an element boundary line, and the region R3 by a divided view only. That is, for the area R1, only the switch 34 is turned on to display the arrow, and the area R1 is displayed.
Since the element boundary line and the contour line are displayed for 2, the switches 32 and 33 are turned on. Further, since only the divided view is displayed for the region R3, only the switch 32 is turned on. As a result, the state of the switch becomes as shown by hatching in FIG. 5 (the hatched portion represents ON. The same applies hereinafter).

With the above settings, the area R1 has A
3, the display attribute of A1 and A2 is given to the area R2, and the display attribute of A1 is given to the area R3.
If the procedure shown in FIG. 3 is displayed in this state, a desired analysis result diagram can be obtained.

In the case of this display method, the elements of the analysis model need to be classified into several groups (in the example of FIG. 2, the elements are classified as elements belonging to the regions R1 to R3). Generally, in many cases, elements are already classified based on the relationship of material distribution and the like, and the elements may be used as they are.

As described above, according to the first embodiment,
The drawing method used to display the analysis result can be set independently for each element. Therefore, it is possible to describe the analysis result expressed by a plurality of drawing methods in one drawing.

Although the hidden image processing is not performed in this embodiment, the hidden image processing using the Z sort method can be easily performed by inserting the following processing between steps S11 and S12. . That is, all polygons are sorted according to the distance from the viewpoint position when displaying. Then, in the loop after step S13, the polygons are displayed in order from the viewpoint position. As a result, the polygon drawn closer to the viewpoint position later overwrites the result of the far polygon drawn earlier, so that the hidden image processing diagram can be finally obtained. Note that such hidden surface processing can be similarly applied to each of the embodiments described below.

<Example 2> In Example 1, the displayed analysis results were the same regardless of the display method. In the second embodiment, different analysis results are displayed for each drawing method.
The basic idea and processing flow in the second embodiment are almost the same as those in the first embodiment. Therefore, here, only different parts will be described with reference to FIGS.

In the second embodiment, the content of the analysis result to be used is set for each display drawing method. That is, for the two display methods of the contour line and the arrow shown in FIG. 2, what to use as the analysis result is individually specified (of course,
For element display, do not specify because the result is not displayed). Then, when drawing contour lines or arrows in steps S15 and S19 of FIG. 3, the drawing is performed using the analysis results designated for each.

FIG. 6 is a diagram showing a display data setting screen in the second embodiment for displaying the analysis model of FIG. In the figure, 30 to 37 are the same as those shown in FIG. 5, and the description thereof will be omitted. Reference numerals 41 and 42 are switches for selecting an analysis result. The switch 41 designates which of the “magnetic field strength” and “magnetic flux density” analysis results the contour line display is applied to. Similarly, the switch 42 designates which of the “magnetic field strength” and the “magnetic flux density” analysis results the arrow display is applied to.

As a result of the above setting, the correspondence information for associating the analysis result with the display projection is formed in the memory 13. Then, in steps S15 and S19 of FIG.
By referring to this correspondence information, the analysis result corresponding to each projection is drawn.

Using this setting screen, the magnetic field strength is displayed by arrows in the region R1, the magnetic flux density is displayed by contour lines with element boundaries in the region R2, and the region R3 is displayed in the model of FIG.
Now, the setting for displaying only the split view will be described.

First, selection of display elements for element display, contour line display, and arrow display is as shown by hatching in FIG.
34). Then, the switches 41 and 42 are used to select the analysis result for the contour line display and the arrow display. Here, the magnetic flux density and the magnetic field strength are respectively selected as the display results applied to the contour line display and the arrow display.

By performing the display according to the procedure shown in FIG. 3 with the above settings, a desired figure can be obtained.

According to the setting screen of FIG. 4, the same analysis result is used for the model surface and the cross section. However, it is obvious that the switches 33, 34, 36, and 37 can be changed so that the results can be easily selected by providing the result selection switches independently.

<Example 3> In Example 2, different analysis results were displayed for each drawing method. In the third embodiment, an example of displaying different analysis results for each element block will be described. The basic idea and processing flow in the third embodiment are almost the same as those in the first embodiment. Therefore, here, only different parts will be described with reference to FIGS.

In the third embodiment, the analysis result to be used individually is designated for each element block designated by the user. Then, in steps S15 and S19 of FIG. 2, drawing is performed using the analysis result designated for the element block to which the polygon belongs.

FIG. 7 is a display data setting screen of the third embodiment for displaying the model of FIG. 30 to 3 in the figure
7 is the same as that shown in FIG. 5, and the description thereof is omitted. 51, 52, and 53 are regions R1, R2, and R, respectively.
A switch for selecting a result used for displaying the polygon representing the model surface of No. 3 and switches 54, 55, 56 for selecting a result used for displaying the polygon representing the cross section of the regions R1, R2, R3, respectively. In FIG. 7, magnetic field strength and magnetic flux density are shown as selectable analysis results.

As described above, the correspondence information for associating each area with the analysis result to be drawn is stored in the memory 13. Then, in steps S15 and S19, the analysis result associated with the area to which the polygon belongs is acquired from the association information and drawing is performed.

Using this setting screen, the magnetic field strength is displayed in contour lines in the region R1, the magnetic flux density is displayed in contour lines with element boundaries in the region R2, and the region R is displayed in the model of FIG.
In Section 3, the setting for displaying only the divided drawings will be described.

First, for the region R1, only the contour switches are turned on (switch 33), and the magnetic field strength is selected as the analysis result to be used (switch 51). Next, for the region R2, the element display and the contour line display are turned on (switches 32 and 33), and the magnetic flux density is selected as the analysis result to be used (switch 52). Finally, regarding the region R3, only the element display is turned on (switch 31). By performing the processing of FIG. 3 with the above settings, a desired figure can be obtained.

According to the setting screen shown in FIG. 7, the same analysis result is used for displaying contour lines and displaying arrows in one area. However, this is the switch 33,3
It is obvious that the result selection switches can be independently provided for the areas 4, 36, and 37 so that the results can be easily selected for the respective areas.

<Fourth Embodiment> In the above first to third embodiments, the boundary line of each element is drawn with respect to the element for which the element display is designated. However, in the actual display, displaying the boundary line of each element often causes too many lines to be displayed, making it difficult to see the analysis results such as contour lines and arrows.
Therefore, in the fourth embodiment, an example will be described in which only the outline of the element for which the element display is designated is displayed.

In general, the outline of an element block can be substituted by a side that is not shared by a plurality of elements (a side that is not adjacent to other elements via that side). That is,
Of the sides representing the shape of each element in the block, the side that is not shared with other elements is extracted and displayed, and the contour line of the element block is obtained. The contour line is the first embodiment.
Then, it is also a part of the element boundary line drawn on the model surface when the element is displayed.

Therefore, in the fourth embodiment, the contour line drawing is incorporated into the display method in the first embodiment as shown in FIG.
FIG. 8 is a flowchart showing the procedure of analysis result display processing in the fourth embodiment. In FIG. 8, the same process steps as those in the first embodiment (FIG. 3) are designated by the same step numbers, and description thereof will be omitted here.

Compared with FIG. 3, steps S61 and S62 are newly added. This step S61, S
62, that is, in the step of drawing the boundary line of the polygon, if the boundary line coincides with the contour line, the contour line is drawn, and if not, the contour line is not drawn and the contour line is drawn. When the method of displaying the outline of the element block is adopted, it is better not to paint the surface to be displayed. Therefore, in FIG. 8, steps S16 and S1 of FIG.
7 is omitted. As a result, in the case of the three-dimensional model, only the outline is displayed, so that a very easy-to-understand diagram can be provided.

Next, an example of displaying the element boundary line by the outline will be concretely described with reference to the model of FIG. Further, the display data setting screen shown in FIG. 5 is used. For the model of FIG. 4, the result of the magnetic material portion is displayed by contour lines, and at the same time, the element blocks of the regions R1, R2 and R3
Also show contour lines.

In this case, the areas R1, R2, R of the switch 32 are set as elements for element display on the setting screen of FIG.
Turn all 3 on. Further, as an element for displaying contour lines, the regions R2 and R3 of the switch 33 are turned on. And other than that, it is turned off.

When the display is performed by setting the switches as described above, in addition to the contour lines of the magnetic material portions (regions R2 and R3),
The region R is obtained by the processing of steps S61 and S62 in FIG.
Each contour line of R1, R2 and R3 is displayed.

Although a specific example has been described here using a two-dimensional model, it is clear that the contour line can be displayed in the same manner in the case of a three-dimensional model.

Further, in the first to third embodiments, the boundary between the elements is displayed as the element display, and in the fourth embodiment, the contour line is displayed. These (display of element boundary line or contour line)
In the setting screen of FIG. 5, it is possible to easily switch in one program by adding a switch for displaying the element boundary line or only the contour line for the element display. .

As described above, according to the first embodiment,
Since a plurality of drawing methods can be used for one display, it is possible to select the optimum display method of the result according to the partial portion of the analysis model, and to provide a very easy-to-understand drawing of the analysis result. In addition, it is now possible to display a single display, which used to require a plurality of displays in the past.
The operability has improved. Furthermore, the number of times of copying what is displayed on a graphic display or the like onto paper is reduced, and paper can be saved.

Further, according to the second and third embodiments, in addition to the effect of the first embodiment, a function of displaying a plurality of kinds of analysis results in one display is added, so that a wider variety of analyzes can be performed. The result can be displayed. Therefore, it is possible to obtain a more understandable diagram, save labor, and save copy paper.

Further, according to the fourth embodiment, since the contour line of the entire analysis model can be displayed at the same time as the analysis result, it is possible to provide a very easy-to-understand diagram of the position of the element displaying the result with respect to the entire analysis model. Became. Especially,
Even in the cross-section display of the result of the three-dimensional model, it is now possible to provide a diagram that allows the position of the cross-section to be easily understood.

Further, as can be understood from the above description, according to the above-mentioned Examples 1 to 4, the three display projection methods (element display,
(Contour line display, arrow display), you can specify the element block to be displayed individually, and display results can be simply associated with each display method or element block, making it extremely easy to make complicated settings. It became so. In particular, by making the display / non-display of the element boundary line a part of the element display, the setting becomes extremely rational, easy to understand, and easy to use.

Further, with respect to the combination of the display method and the display portion, the element block to be displayed can be designated on one screen, which makes the setting method extremely easy and easy to understand.

<Embodiment 5> Next, an apparatus for automatically and sequentially displaying a plurality of analysis result diagrams according to the drawing parameters set respectively will be described.

FIG. 9 is a block diagram showing the arrangement of a computer for displaying the analysis result in the fifth embodiment. In the figure, the same components as those in Embodiment 1 (FIG. 1) are designated by the same reference numerals, and the description thereof will be omitted. Reference numeral 93 is a memory, which is shown in FIG.
In addition to having the same function as the memory 13 of
3 has a memory area. Various drawing parameters set for drawing processing are stored in M91 to M93. M91 stores information indicating the type of contour line used for displaying the result (whether to display only the lines showing the contour lines or to fill the space between the contour lines with a different color for each level). M92 stores information designating how many contour lines are to be displayed. Information indicating the level value between the contour lines is stored in M93. In the present embodiment, description will be made using the above three drawing parameters, but the drawing parameters are not limited to these, and various generally known drawing parameters can be used.

The external memory 94 stores an environment file and an execution file instead of a general restart file. The environment files F41 to F44 are files in which drawing parameters are recorded for each drawing unit. The execution file F45 defines the order of use of the environment files F41 to F44 when drawing is executed.

FIG. 10 is a block diagram showing the functional arrangement relating to the analysis result display of the computer in the fifth embodiment. In the figure, reference numeral 100 denotes a central control unit, which represents a unit that controls the entire apparatus. A drawing parameter setting unit 101 sets various drawing parameters described above. A drawing unit 102 draws an analysis result on the graphic display 11 according to a drawing command from an analyst or a restart file. A file input / output unit 103 inputs / outputs files to / from the external memory 94. An automatic display file creation unit 104 is a part that creates an automatic display file (environment file and execution file) for automatically displaying the analysis result. 1
Reference numeral 05 denotes an automatic display file execution unit, which uses the automatic display file created by the automatic display file creation unit 104
Through the drawing unit 102, the graphic display 11
This is the part that displays the analysis results.

Next, referring to FIG. 11 and FIG. 12, the fifth embodiment will be described.
Will be described. FIG. 11 is a flowchart illustrating a processing procedure of the automatic display file creation unit 104 according to the fifth embodiment. In addition, FIG. 12 is a flowchart illustrating a processing procedure of the automatic display file execution unit 105.

First, the processing of the automatic display file creation unit 104 will be described with reference to FIG. The apparatus according to the fifth embodiment has two modes, that is, a mode for creating an automatic display file and a mode for not creating the automatic display file, and the automatic display file is created in the mode for creating. When the analyst draws the result in the mode of creating the automatic display file, the processing of FIG. 11 is automatically executed by the automatic display file creating unit 104 each time.

(1) The drawing parameters set in the drawing are output to the external memory 94 as one environment file (step S101). The drawing parameters referred to here are parameters associated with the above-described various drawing methods for displaying the analysis result on the display 11, and are stored in M91 to M93 in FIG. The drawing parameters output here may be all the drawing parameters of the display system of the device, or may be only those related to the drawing method in which the drawing is being performed. The environment file is created in the external memory 94, as indicated by F41 to F44 in FIG.

(2) Step S1 in the execution file F45
The name of the environment file created in 01 is recorded (step S102). If the environment file name is already recorded in the execution file F45, it is additionally recorded at the end. Therefore, in the execution file F45, as many names as the number of environment files stored in the external memory 94 are recorded. The execution file F45 is also
It is created on the external memory 94.

Note that the automatic display file creation unit 1 described above is used.
The timing for creating the automatic display file according to 04 may be immediately before or after displaying the analysis result.

Next, the processing of the automatic display file executing section 105 will be described with reference to FIG. In order to automatically display the analysis result, the execution file F45 is read via the file input / output unit 103 in FIG. 10 and executed according to this.

(1) When the execution file F45 stored in the external memory 94 is read out via the file input / output unit 103, the processing shown in FIG. 12 is started. First, one environment file name is read from the read execution file F45 (step S111).

(2) The environment file having the environment file name obtained in (1) is read from the external memory 94 via the file input / output unit 103. (Step S112).

(3) The values of the drawing parameters (M91 to M93 in FIG. 9) of the apparatus are set according to the drawing parameters stored in the environment file read in (2) (step S113).

(4) The analysis result is drawn on the display 11 based on the drawing parameters set in M91 to M93 (step S114).

(5) The above processes (1) to (4) are automatically repeated for the number of environment file names described in the execution file (step S115). In (1), the environment file name is read in order from the beginning of the file.

Next, the operation of the apparatus according to the fifth embodiment will be described with reference to FIG.
Drawing numbers Z1 to Z4 using drawing parameters as shown in
Will be described more concretely by taking as an example the case of continuously displaying.

First, the process of creating an automatic display file will be described. Similar to creating a general restart file,
The automatic display file is automatically created by displaying the drawing numbers Z1 to Z4. The operation content and the process of the automatic display file creation unit 104 will be described below.

(1) The analyst, as the drawing parameters (M91 to M93 in FIG. 9), type A1, number B1,
Set the level value to C1. In this operation, the drawing parameter setting unit 101 displays a menu on the display 11, and the input unit 1 is operated through the displayed menu.
5 is used. In the menu, items and options of drawing parameters (type, number of contour lines, value of each level, etc.) as described in the related art are displayed. As a result, knowledge about the code for setting the drawing parameters and a text editor are unnecessary. When the drawing parameters have been set as described above, the analysis result is displayed on the display 11 (drawing number Z1). At this time, the drawing parameters set in M91 to M93 are output to the external memory 94 via the file input / output unit 103. As a result, FIG.
Environment file F41 (Type = A1, Number = B
1, the level value = C1) is automatically created (step S101). The name of the environment file F45 created here is automatically recorded in the first line of the execution file F45 in FIG. 9 (step S102).

(2) Next, the drawing number Z2 is displayed.
By the same method as (1), the analyst edits the drawing parameter of the apparatus by the drawing parameter setting unit 101 and changes the type (M91) to A2. As a result, the drawing parameters M91 to M93 become A2, B1 and C1, respectively,
The drawing number Z2 is displayed according to this parameter. At this time, the drawing parameters in the memory 93 are output to the external memory 94 via the file input / output unit 103. As a result, the environment file F42 (type =
A2, number = B1, level value = C1) are automatically created (step S101). Also, the execution file F45
The name of the environment file F42 created here is automatically added following the name of the environment file F41 (step S102).

(3) The analyst similarly displays the results for the drawing numbers Z3 and Z4. As a result, the environment files F43 and F44 in FIG. 9 are automatically created, and the names of the environment file F43 and environment file F44 created here are added to the execution file F45. By the above operation, the environment files F41 to F4 shown in FIG.
4 and the execution file F45 are created.

Next, the process of automatic display, that is, the operation when the automatic display file execution unit 105 is executed will be described. The automatic display file execution unit 105 reads the execution file F45 created by the above process of the automatic display file creation unit 104, and sequentially executes display. The processing content will be described below.

(1) First, the environment file name (name of the environment file F41) in the first line of the execution file F45
Is read (step S111). (2) The drawing parameters (type = A1, number = B1, level value = C1) in the environment file F41 are read (step S112). (3) The drawing parameters (M91 to M93 in FIG. 9) are set according to the drawing parameters read in (2) (step S113). That is, the type is set to A1, the number is set to B1, and the level value is set to C1. (4) In this state, the analysis result is drawn (step S114). This drawing corresponds to the drawing number Z1 in FIG. (5) Lines 2-4 of the executable file (environment file F4
2 to F44), the same processing is performed (step S115). As a result, the drawings with the drawing numbers Z2 to Z4 are sequentially displayed. (6) When the drawing of the drawing number Z4 is drawn, all the display is completed (step S115), and this processing ends. Through the above processing, the processing of the drawing numbers Z1 to Z4 is automatically and sequentially displayed.

Next, a method of changing a part of the contents of automatic display will be described. In order to change the contents of the automatic display in the device of the fifth embodiment, the environment file for the corresponding display may be updated. For that purpose, a desired environment file may be newly created and replaced with the environment file to be changed. The procedure is described below.

(1) Rendering parameters (Z
4 M91-M93) to the desired values. This operation is performed using the input unit 15 through the menu displayed on the display 11 under the control of the drawing parameter setting unit 101 as described above.

(2) Display the result in the mode for creating an automatic display file. As a result, a new automatic display file (environment file and execution file) is created in the external memory F9.
Automatically created in 4.

(3) The environment file to be changed in the external memory 94 is replaced with the environment file newly created in (2). After the replacement, by executing the execution file in the same procedure as before the above change, the desired result display can be obtained.

The value of the level in the drawing number Z3 of FIG.
A specific procedure for automatically displaying the drawing numbers Z1 to Z4 instead of 2 will be described below with reference to FIG. In FIG. 14, the same components as those in FIG. 9 are designated by the same reference numerals.

(1) The drawing parameters are type = A2,
The number is set to B2 and the level value is set to C2. As a result,
Type = A2, number = B2, and level value = C2 are stored in M91 to M93 of the memory 93.

(2) Display is performed in a mode for creating an automatic display file. As a result, the environment file F51 and the execution file F52 are newly created in the external memory 94.

(3) The environment file F43 in FIG. 9 is replaced with the environment file 51 newly created in (2).
This updated the environment file. After that, the execution file may be executed by the same procedure as before the update.

As described above, according to the fifth embodiment, when the drawing parameters are changed in the automatic display, each drawing parameter is set independently for each display. Therefore, it is necessary to change only the drawing parameter to be changed. Good. For this reason,
Operability is significantly improved.

<Sixth Embodiment> In the fifth embodiment, a new automatic display file is created in order to change a part of the contents of the automatic display. In the sixth embodiment, the environment file of the analysis result display (drawing number) to be changed is directly read into the memory 93,
A method for updating will be described.

In the sixth embodiment, an environment file input / output unit is added to the configuration of the apparatus shown in FIG. 10 (the illustration is omitted due to a slight change). As is clear from the description of the fifth embodiment, the drawing parameters of the apparatus (M91 to M9 in FIG. 9) are
Although 3) corresponds to the contents of the environment file, this environment file input / output unit performs input / output as follows between the device and the environment file.

(1) At the time of output: All drawing parameters of the apparatus are output as an environment file. (2) At the time of input: The drawing parameters are read from the environment file, and the drawing parameters possessed by the apparatus are reset accordingly. In this way, the environment file input / output unit specializes in inputting / outputting environment files, can specify and read a desired environment file, and after changing this, overwrite the existing corresponding environment file. You can

Next, using this environment file input / output unit,
An operation procedure for changing a part of the contents of automatic display will be described.

To change the contents of the automatic display, the environment file for the corresponding display may be updated. FIG. 15 shows the procedure of this update performed by the analyst. The individual steps will be described below.

(1) The environment file to be changed is read through the environment file input / output unit (step S12).
1). By this operation, the drawing parameters (M91 to M93 in FIG. 9) of the apparatus are changed by the environment file input / output unit.
It is automatically set according to the drawing parameters read.

(2) The drawing parameters M91 to M93 are set to desired values (step S122). This operation is performed by the analyst as in the fifth embodiment by displaying a menu on the display 11 under the control of the drawing parameter setting unit 101 and using the input unit 15 via this menu.

(3) The analyst writes the drawing parameter of the apparatus with the same name as the environment file name read in (1) through the environment file input / output unit (step S123). After the update, by executing the execution file in the same procedure as before the update, the desired figure can be obtained.

When the level value of the drawing number Z3 in FIG. 3 is changed to C2 and the drawing numbers Z1 to Z4 are automatically displayed, the specific operation performed by the analyst is as follows. That is, (1) the environment file 3 shown in FIG. 3 is read (step S121). (2) The drawing parameter setting unit 101 changes the level value to C2 (step S122). (3) The drawing parameters on the device are written out under the name of environment file 43 (step S123). You can update the existing environment file by the operation.
After that, the execution file may be executed by the same procedure as before the update.

As described above, according to the sixth embodiment, the setting of drawing parameters on the apparatus can be minimized. For example, in the case of the drawing number Z3 in FIG. 13 described above, in the fifth embodiment, all the drawing parameters such as the type, the number of lines, and the value of the level are reset.
Only the changed part (level value) will be required.

In the fifth and sixth embodiments, only the case of displaying contour lines has been described, but the application of the present invention is not limited to this. For example, an analysis result display by another representation method such as an arrow, a modified drawing, or a graph can be automatically displayed by the same procedure. Not only the result representation method, but also the viewpoint position for display, the enlargement / reduction ratio, the display position on the graphic screen, the hidden surface processing method, the perspective method,
A drawing method such as a semi-transparent display method can be treated as the same drawing parameter and automatically displayed.

As described above, according to the fifth and sixth embodiments, the analysis result can be easily displayed automatically, and
Regarding the partial change of the display contents, the conventional problem was solved as follows. That is, (1) a text editor is not required because the drawing parameters are set by the menu display of the drawing parameter setting section. (2) The code system corresponding to the operation is no longer needed, and its knowledge is no longer needed. (3) To change the drawing parameters related to a certain drawing number, the environment file of the drawing number needs to be changed, so there is no need to search for the changed part. (4) Drawing parameters are stored in an independent environment file for each drawing number, so when a part of the display is changed, it does not affect other parts. As a result, the contents of automatic display can be changed extremely easily.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of one device. Needless to say, the present invention can be applied to a case where the present invention is achieved by supplying a program to a system or an apparatus.

As described above, according to the present invention,
Various analysis results can be output with a simple operation.

Further, according to the present invention, it is possible to display the results in one drawing by a plurality of projection methods, or it is possible to display a plurality of kinds of analysis results in one drawing, which is versatile and flexible. The analysis result can be drawn.

Further, according to the present invention, it is possible to draw a boundary line or a contour line of each element, and to draw a diagram in which the position of the portion displaying the analysis result in the entire analysis region is easily understood. Become.

Further, according to the present invention, the analyst can easily automatically display the analysis result and can easily change the contents of the automatic display.
