Description

  The present invention relates to a general-purpose analysis system used in the field of computer simulation for evaluating the quality of products such as strength and rigidity, and in the field of computer simulation for examining designs for improving drawing quality.

  In the case of using the CAE analysis technique in designing various products, conventionally, analysis specialists have designed products by performing complex intensity calculations and the like. In other words, since CAE analysis is based on physical laws expressed by differential equations, the user is required to understand differential equations and understand mathematical promises that are inevitably required for numerical analysis. Not everyone could easily perform CAE analysis.

  By the way, not only CAE analysis but also a technique for improving operability in various analyzes has been proposed (see, for example, Patent Document 1).

  The technique disclosed in Patent Document 1 stores and saves an analysis operation procedure, and automatically performs analysis based on the stored contents. This eliminates the trouble of repeating the same operation procedure every time the analysis is performed, leading to an improvement in the operability of the analysis (this is referred to as Conventional Technology 1).

In addition, a general-purpose analysis system such as I-deas (registered trademark) developed by SDRC and occupying a large market in Japan is also provided. It is made to select (this is called prior art 2).
JP-A-10-303267

  However, in the individual correspondence type navigation system as seen in the above-mentioned prior art 1, the navigation is most suitable for each product and the analysis know-how is described, but it is usually not possible to change it later. However, there was a problem of using it for versatility. The individual navigation system is very easy to use and does not require any know-how for its use. On the other hand, since it takes time to create software, there is a problem that the cost becomes very high.

  Moreover, in the above-described general-purpose analysis system of Prior Art 2, there is no display part for know-how such as how to cut meshes, selection of boundary conditions, how to interpret analysis results, etc. There was a problem that analysis had to be done by listening to experts. Therefore, there is a problem that it is necessary to study analysis know-how separately.

  By the way, the present applicant provides a CAE analysis system in Japanese Patent Application Laid-Open No. 2001-2908446 that allows a designer to easily perform CAE analysis. However, this system still has a problem that it is necessary to create a system for each product. In addition, after CAE implementation, it was necessary to prepare a CAE report. Japanese Patent Application Laid-Open No. 11-66132 provides a system that can refer to past CAE cases. However, even in this system, it is necessary for an analysis operator to input CAE information.

  Further, a general-purpose CAE system that automatically outputs a report is commercially available, but the output report needs to be managed by the user and cannot be used as a past case database.

  The present invention was devised to solve such problems. The purpose of the present invention is to make the general-purpose operation part a general-purpose work procedure in the form of a navigation, so that the general-purpose operation part can be used universally and a report output of analysis results can be obtained. It is possible to provide a general-purpose analysis system that can use report results as a past case database.

  The general-purpose analysis system of the present invention is a general-purpose analysis system that sequentially executes CAE analysis analysis procedures such as shape creation or CAD file reading, mesh division, material property value setting, boundary condition setting, and analysis execution. Display means for displaying the analysis procedure screen of the object, input means used when operating any item in the analysis procedure screen displayed on the display means, and each analysis according to the input operation by the input means Screen display control means for sequentially displaying a procedure screen on the display means, analysis information storage means for storing information such as analysis conditions input by the input means from the analysis procedure screen displayed on the display means, and the analysis Analysis calculation processing means for performing analysis in accordance with information such as analysis conditions stored in the information storage means, and CAE analysis results executed by the analysis calculation processing means. A past case storage means for storing a past case as a past case, and a past case search means for searching for a past case stored in the past case storage means. The analysis procedure screen corresponds to the analysis content. A button for referring to a past case is provided, and when the past case search means is selected by the input means, the past case corresponding to the analysis content is searched from the past case storage means, It is characterized by being superimposed on the analysis procedure screen displayed on the display means.

  In the general-purpose analysis system of the present invention, in the above configuration, when the button is selected by the input means, the past case search means displays a past case search screen for searching for a corresponding past case. When the search item is input from the input means to the past case search screen, the corresponding past case is searched from the past case storage means according to these input conditions. And it is characterized in that it is displayed superimposed on the analysis procedure screen displayed on the display means.

  According to the present invention having such a feature, CAE can be executed while referring to past analysis results as past cases. Therefore, troublesome CAE considerations such as mesh type and mesh division are omitted for analysis of cases similar to the past. it can. Thereby, CAE examination and evaluation time can be shortened. Also, time for inputting past case information becomes unnecessary.

  According to the general-purpose analysis system of the present invention, buttons for referring to past cases are appropriately prepared at the key points of each analysis procedure screen. At the processing stage, past cases related to the work can be referred to at any time. Thus, since CAE can be executed while referring to past analysis results as past cases, troublesome CAE considerations such as mesh type and mesh division can be omitted in analysis of cases similar to the past. Evaluation time can be shortened.
