PURPOSE: To shorten the time required to enlarge and reduce the graphic display by finding an integrated numerical analytic result consisting of all numerical analytic results and making a composite visual graphic display of a physical phenomenon corresponding to a numeral group based on the integrated numerical analytic result. CONSTITUTION: After an initial screen is displayed, the number of the analytic results is specified through an input device (301) and the numeric input of geometric data and analytic data constituting the integrated analytic result are repeated (302); when the specified number of kinds of the analytic results is >=2 (304) after the input of the numerals ends (303), processings regarding a composite display are performed (305-308). Then a graphic display processing for the geometric data and analytic data is performed (309) and when a display is made again at another angle (310), the graphic display processings are repeated. To respecify the arrangement of whole system data and partial system data, a return to the composite display processing is made and the processing is repeated. To display new data (312), a return to the start is made and numerals are inputted.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a figure of a numerical analysis result, and more particularly to a method for displaying a figure of a numerical analysis result which enables easy and quick evaluation of the numerical analysis result.

[0002]

2. Description of the Related Art A numerical analysis method is a method for predicting in advance the flow performance of a fluid device or the thermal performance of an electronic device by performing a numerical calculation at a high speed by a computer, and a physical phenomenon is actually calculated. This is a very effective method together with the experiment to generate. However, the numerical analysis result obtained by performing the numerical analysis method is only an enumeration of numerical values, so the physical phenomena that may occur will be understood by simply looking at the numerical analysis results and It is extremely difficult to predict the performance of products such as devices. Therefore, conventionally, the obtained numerical analysis result is converted into a contour map or a vector diagram indicated by an arrow by a computer, and this is graphically displayed by using a plotter or a display device, and the physical equivalent to the numerical analysis result is obtained. Efforts have been made to facilitate understanding and evaluation of phenomena. Furthermore, by making it possible to enlarge and reduce the graphic display, local evaluation of important points in the numerical analysis result is facilitated.

In recent years, as the performance of various types of hardware constituting computers has improved, complex analysis of large-scale environmental problems, vehicle movement problems, whole products, etc., and coupled analysis of noise, fluid, structure, heat, etc. The above numerical analysis method is being applied to the above. Generally, when such a composite analysis or a coupled analysis is performed, two or more types of numerical analysis results, each of which is composed of separate geometric data and analysis data, are obtained.

FIG. 6 is a diagram showing an example of the concept of complex flow analysis in the purification problem of a lake. In FIG. 6A, when performing the flow analysis when the purifying device 6 is installed in the region 61 near the central portion of the lake 60, FIG.
As shown in (b), the entire lake 60 (whole system data)
And a numerical analysis of only the peripheral area 61 of the purification device 6 (partial system data) are separately performed to obtain an overall rough numerical analysis result 60a and a partial more detailed numerical analysis. After obtaining the result 61a, the physical phenomena corresponding to the respective numerical analysis results 60a and 61a are comprehensively grasped and evaluated.

FIG. 7 is a flow chart schematically showing the flow of a conventional method of displaying a figure of a numerical analysis result. In the figure, first, an initial screen for instructing the input of geometric data and analysis data forming the numerical analysis result is displayed (step 701), and then one of two or more types of numerical analysis results (FIG. 6). In the case of, the input instruction of the geometrical data and the analysis data forming one of the numerical analysis results 60a and 61a described above and the input of specific numerical values are executed (step 702). Then, based on the input geometric data and analysis data, various processes necessary for displaying the figure of the numerical analysis result are performed (step 70).
3). After that, when "redisplay" is selected in step 704, the process returns to step 703, the display method is changed, and the graphic display based on the same numerical analysis result is performed again. If "display new data" is selected in step 705, the process returns to step 702 to input the geometric data and analysis data that form one of the different numerical analysis results and to input a specific numerical value. Repeat from input.

FIG. 8 is a diagram showing a screen display example when the two types of numerical analysis results obtained by the composite analysis of FIG. 6 are graphically displayed in accordance with FIG. 7, and on the left side of the display screen 1. Numerical analysis result 60 in window 21
The graphic display 21a of the entire system based on the geometric data and the analysis data forming a is displayed in the right window 22 and the graphic display 22a of the partial system based on the geometric data and the analysis data forming the numerical analysis result 61a. , Respectively.

FIG. 9 is a diagram showing a screen display example when enlarging the graphic display of the subsystem shown in FIG.
6 is a flowchart schematically showing the flow of window conversion processing accompanying enlargement or reduction of a graphic display. That is, when the graphic display is enlarged or reduced in order to locally evaluate an important part in the numerical analysis result, for example, as shown in FIG. 9A, the area 221 to be enlarged in the window 22 is moved by a mouse or the like. When an instruction is made by enclosing the area in a rectangular area (step 1001), a predetermined scaling (step 1002) and display coordinate conversion (step 1003) are performed accordingly, and then the area 221 is displayed as shown in FIG. 9B. Enlarged window 2210
Will be newly opened.

In the graphic display of the numerical analysis results according to the above-mentioned prior art, the graphic display is performed in a separate window for each of the two or more types of numerical analysis results obtained by the composite analysis or the coupled analysis. However, since it was not possible to simultaneously superimpose all the composite or coupled numerical analysis results that interfere with each other in a graphic display, there is the problem that it is difficult to evaluate the analysis results such as the sequence of flows. It was

Further, when the graphic display is enlarged or reduced in order to perform local evaluation of important points in the numerical analysis result, all the geometric data and the analysis data constituting the numerical analysis result in the above-mentioned prior art. Since the coordinate conversion processing is performed for the above, if the graphic display is repeatedly enlarged and reduced on a computer that does not have high hardware performance related to graphic display, most of the work time required to evaluate the numerical analysis results will be the above graphic display. There is a problem that it is occupied by time and the work efficiency of evaluating the numerical analysis results decreases.

Therefore, an object of the present invention is to solve the above-mentioned problems and to make it possible to simultaneously superimpose two or more types of numerical analysis results obtained by a composite analysis or a coupled analysis and display them graphically. It is an object of the present invention to provide a method of displaying a figure of a numerical analysis result that can reduce the time required for enlarging and reducing the size regardless of hardware performance.

[0011]

In order to achieve the above object, a method of displaying a figure of a numerical analysis result of the present invention is a numerical analysis calculated by applying a predetermined numerical calculation process to a given numerical group. Based on the result, in the figure display method of the numerical analysis result for displaying the visualized figure of the physical phenomenon corresponding to the numerical value group, any one of the following three processing procedures is executed.

For each partial system data, all calculated by deleting the overlapping part with the partial system data in the whole system data according to the layout relationship of the partial system data with respect to the whole system data and replacing it with the partial system data. An integrated numerical analysis result is obtained by integrating the numerical analysis results of. Based on the result of the integrated numerical analysis, a composite visualization graphic display of physical phenomena corresponding to the numerical value group is performed.

[Procedure 2] From the analysis result numerical value group constituting the numerical analysis result, the enlarged display target analysis result numerical value group included in the arbitrarily designated enlarged display area in the visualization figure display is selected. Select. Based on the numerical analysis result for magnifying display obtained by applying a predetermined magnifying conversion process to the numerical value group of the magnifying display target analysis result, the visualization graphic display of the physical phenomenon in the magnifying display area is performed.

[Procedure 3] to are the same as [Procedure 1] described above. From the analysis result numerical value groups forming the integrated numerical analysis result, a magnified display target analysis result numerical value group included in the arbitrarily designated magnified display area in the visualization figure display () is selected. Based on the numerical analysis result for magnifying display obtained by applying a predetermined magnifying conversion process to the numerical value group of the magnifying display target analysis result, the visualization graphic display of the physical phenomenon in the magnifying display area is performed.

[0015]

The operation based on the above configuration will be described.

In the method of displaying a figure of a numerical analysis result of the present invention, based on the numerical analysis result calculated by applying a predetermined numerical calculation process to a given numerical group, the visual observation of the physical phenomenon corresponding to the numerical group is performed. In the method of displaying the figure of the numerical analysis result for displaying the converted figure, any one of the above-described three processing procedures is executed.

Here, when [Procedure 1] is executed as a processing procedure, two or more kinds of numerical analysis results that interfere with each other obtained by the composite analysis or the coupled analysis are put together, and are simultaneously superposed and graphically displayed. As a result, it is possible to easily evaluate the analysis result such as a series of flows.

When [Procedure 2] is executed as the processing procedure, the enlargement conversion processing is performed only on the local numerical analysis result (enlarged display object numerical group) included in the arbitrarily designated enlarged display area. Since the time required to expand and contract the graphic display is shortened regardless of the hardware performance, the expanded display area can be displayed in detail in a shorter time than before, and the numerical analysis results can be evaluated. Work efficiency can be improved.

Further, when [Procedure 3] is executed as the processing procedure, it becomes possible to collect two or more kinds of numerical analysis results and display them as a graphic at the same time as in [Procedure 1]. , It is possible to easily evaluate the analysis results such as a series of flows, and also regarding the graphic display after superposition, the time required for enlarging and reducing the graphic display is the same as in [Procedure 2] above. Since it is shortened regardless of the hardware performance, the enlarged display area is displayed in detail in a shorter time than in the past, and the efficiency of the numerical analysis result evaluation work can be improved.
