摘要： The conventional technologies are impractical for the following reason. CAD has been the only solution for changing an analysis model with adding or deleting a fillet. In this case, it is necessary to repeat the mesh generation and condition configuration, which makes the work time longer especially for large-scale or complicated shape data. The present invention, accomplished to solve the above-mentioned problem, provides an analysis mesh generation apparatus including a computer for generating a mesh model. The apparatus is configured to create a screen for selecting an edge of a mesh model and entering a radius of a fillet to be applied to the selected edge; and to create a screen for generating a mesh for the applied fillet, generating a new mesh model by deleting or adding an area enclosed by a contour of the mesh model and the fillet, and displaying the new mesh model.
摘要翻译：传统技术是不切实际的，原因如下。 CAD是通过添加或删除圆角来更改分析模型的唯一解决方案。在这种情况下，需要重复网格生成和条件配置，这使得工作时间更长，特别是对于大规模或复杂的形状数据。为了解决上述问题而实现的本发明提供了一种包括用于生成网格模型的计算机的分析网格生成装置。该装置被配置为创建用于选择网格模型的边缘并输入要应用于所选边缘的圆角的半径的屏幕; 并创建用于生成应用圆角的网格的屏幕，通过删除或添加由网格模型和圆角的轮廓包围的区域并显示新的网格模型来生成新的网格模型。

摘要： An analysis model producing/assisting apparatus produces a recognition model, approximating surfaces of configuration and ridgelines thereof by planes and lines, from a configuration model showing the configuration. Thereafter, it produces a mapping model through dividing the recognition model into cubic grids, and then produces an analysis model, through mapping grid points of the mapping model onto the configuration model. When producing the recognition model, know-how for producing the analysis model, which gives an influence upon quality of the meshes of the analysis model, is take out from a database, and that know-how for producing the analysis model is applied onto the configuration model.
