Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analysis data input / output device capable of interactively operating analysis data such as a finite element method, a boundary element method and a difference method.

[0002]

2. Description of the Related Art In recent years, with the improvement of computer performance,
Numerical experiments such as finite element method and difference method are widely used as one method for design, and their importance is increasing year by year. In such a numerical experiment, an element division model in which the model is divided into fine elements is used.

In handling a divided model, an analyst is required to have information such as elements and nodes (points of nodes connecting elements) as a part of constituent elements. Various input / output devices (pre-post) are currently being developed so that such information can be interactively provided.

FIG. 4 shows the configuration of a computer that performs input / output processing. The computer is generally a central processing unit 43.
, Graphic display 46, and first input unit 47
And a second input unit 48 and an external storage device 49.

The central processing unit 43 is a CPU (central process).
ing unit) 44 and a memory 45. Generally, the first input section 47 is a keyboard and the second input section 4
8 indicates a mouse. The command from the analyst is input through these input units, processed by the central processing unit 43, and then the answer is displayed on the graphic display 46. Further, the data on the memory 45 is stored in the external storage device 49 in the form of a file as needed.

Further, in recent years, a window system is often used as an environment (interface) for an analyst to interactively perform processing on a computer. For example, in UNIX systems, X Window (Ryoichi Kinoshita: X-
Window Ver.11 Programming, Nikkan Kogyo Shimbun, 1989
Are often used. Furthermore, as a library for developing programs using X windows, Mo
tif (Kabuki et al .: X-WindowOSF / Motif programming,
Nikkan Kogyo Shimbun, 1990, etc.), Open Look, etc.
I / O programming developers can use these libraries to create menus for controlling programs,
Switches and buttons can be easily created and arranged.

In general, the analyst often uses a part of the analysis data (including the analysis result) to perform further calculation. For example, in the case of magnetic field analysis, the force acting on the magnetic body is calculated from the result of the magnetic field distribution, or the inductance of the coil is calculated. Here, these calculations are
We will call it the next calculation. In these secondary calculations, a part of the analysis data is required, and the input / output device is used to extract the required data.

FIG. 5 is a flow chart showing a processing procedure until the secondary calculation by the CPU 44 shown in FIG.

Here, it is assumed that a part of the node coordinates (node numbers 1, 3, 5, 6, 9, ...) Of the analysis data are used as input data for the secondary calculation. Further, it is assumed that the split model is displayed in the window 61 shown in FIG.

By operating the first input section 47, a list output destination is designated (S71) and a node is designated (S72).
Then, the CPU 44 retrieves the coordinates of the designated node from the memory 45 (S73). The designated list output destination is determined (S74), and if the determination result is that the output destination is a window, the coordinate values obtained by the search are displayed in the window 63 (S75). On the other hand, if the result of determination is that the output destination is a file, the coordinate values obtained by searching are stored in the external storage 49 (S76).

Then, it is determined whether or not a new node list is to be displayed. If the determination is affirmative, the process returns to S72.

By the above processing, the coordinate values of the desired node are displayed in the window 63, as shown in FIG. Or it will be output to a file.

On the other hand, if a negative decision is made, the process proceeds to the secondary calculation process. Generally, the input data for the quadratic calculation is given from a file. Therefore, it is necessary to convert the coordinate values displayed in the list into a file by some method and input it.

First, the output destination of the coordinate value is determined (S7
8) If the result of determination is that it is the graphic display 46, file data is created using a text editor based on the data displayed in the window 63 (S79). This work involves reading the displayed data with the eyes and operating the first input unit 47 to
It is done manually. At this time, the format of the data on the file (format: position where each data is arranged (row number and column number)) is the input format of the program that performs the secondary calculation (hereinafter referred to as the data input format of the secondary calculation). Must be matched with. On the other hand, if the list output destination is a file, it is edited according to the input data format of the secondary calculation using an editor (S80).

Then, a secondary calculation is performed using the file thus created (S81).

Although the example of using the coordinate value of the node as the input data of the secondary calculation has been described above, the number of the node forming the element, the value of the result at the element or the node, etc. Even when various items of information are used as input data, the secondary calculation can be performed in the same procedure.

[0017]

However, the analyst must read the data displayed in the list one by one and type while paying attention to the input data format. There was also something to do.

When the list output destination is a file, it is very troublesome to change the data format of the file by using a text editor. In addition, the data could not be visually confirmed at the designated time point, and errors were often made. If the data was specified incorrectly, it was necessary to re-specify it from the beginning or to make a separate record and make a correction when the file was edited after the data was specified.

An object of the present invention is to solve the above problems and to provide an analysis data input / output device which can improve workability and work efficiency and work reliability. It is in.

In the present invention, the text image displayed by the coordinate value display control means is saved as a file by the saving means.

[0025]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. In FIG. 1, reference numeral 11 is a designation section for designating a required data portion. Reference numeral 12 is a search unit that searches the memory for the data designated by the designation unit 11. An edit unit 13 has an edit screen on which processing such as data deletion and insertion can be performed, and text data is edited on the edit screen. A file storage unit 14 stores the data on the editing screen of the editing unit 13 as a file. Reference numeral 10 denotes a main body, which controls each part.

Next, the operation of the input / output device will be described.

When the data is designated, the retrieval unit 12 retrieves the content of the data from the memory. Then, the search results are displayed as a text image in a list on the editing screen of the editing unit 13.

The analyst edits the data displayed on the editing screen by using the editing unit 13 and changes it to the input data format of the secondary calculation. Save the edited data in the file storage unit 1

The text widget 26 is editable. Reference numeral 24 denotes a button, which is used to issue a file saving command to the file saving unit and is created by a button widget. Reference numeral 23 is a window. Reference numeral 25 is a button for deleting all the list data displayed on the edit screen at once. 27
Is a scroll bar.

FIG. 3 is a flow chart showing the procedure until the secondary calculation is performed. This is the nodal coordinate value of the split model displayed on the graphic display shown in FIG.
This is an example used as input data for the next calculation.

Division model 2 displayed in window 21
The node whose coordinate value is to be known is designated by using 2 (S3
2), and is searched by the search unit 12 (S33). Then, the character strings in the display list are made into a one-dimensional array (stream data), sent to the text widget, and the search results are displayed on the edit screen 26 (S34). The specific display method is (Kabuki et al .: X-Window OSF / Motif programming, Nikkan Kogyo Shimbun, 1990 (first edition), pp150-185).
The method is the same as that described in.

After that, S32 to S34 are repeated for all required nodes. Then, the content of the data displayed on the edit screen is changed (edited) to the data input format of the secondary calculation (S37). It should be noted that this editing function is a function unique to the text widget, and as the creator of the input / output device, the specification as the editing function can be satisfied simply by using the text widget as the editing screen of the editing unit. . Then, when the save button 24 is pressed after the editing is completed, the file saving unit is activated to save the content displayed on the edit screen in a file (S38). This file save function also saves the data displayed on the screen as part of the function of the text widget.
Since it can be imported as a character string of the next array, it is used.

After that, the saving is completed by outputting the data of the one-dimensional array to a file. Then, a secondary calculation is performed using the saved file (S39).

The position at which the node information is displayed on the text widget may be either the final position of the displayed text or the position where the cursor is. When the last position of the text is set, the newly displayed node information is always added to the last line, which is simple and easy for the analyst to understand. On the other hand, when the cursor is at a certain position, the analyst can move the position of the cursor in advance to insert the newly displayed node information at an arbitrary position in the text.

Further, the function of the editing section may include a clear button 25 shown in FIG. This clear button is for deleting all the list data displayed on the edit screen at once, and the realizing means is almost the same as the method of displaying characters on the text widget in S34. That is, here, one null may be set as the character string to be displayed. That is, by pressing the clear button 25, one new (not added) null character is newly displayed in the text widget. Execute the clear button 25 before S32, or S
By performing the process between 32 and S35, the analyst can clear all the data that has been displayed so far, and can newly display and handle the information.

In this embodiment, the example in which the nodal coordinate values of the finite element method analysis model are used as the input data of the quadratic calculation has been described. Not only other data about the split model of, but also data of other analysis methods,
It goes without saying that it can be used in the same manner.

Also, an example using the UNIX X window system has been described, but the present invention is not limited to this, and it goes without saying that another system can be used.

In the present embodiment, an example in which nodes are used as partial components has been described, but elements, faces of elements, and sides of elements may be used.

[0040]

As described above, according to the present invention,
Since the information displayed in the list can be directly edited on the screen and saved as a file in the external storage device, the labor and time are greatly reduced, and workability and work efficiency are further improved.
