METHOD AND DEVICE FOR GENERATING MESH FOR NUMERICAL ANALYSIS

摘要

PURPOSE: To easily generate a mesh or control the shape and layout of the mesh even in a complicated shape model by displaying the allocating directions of respective segments of the shape model by a recognition model generation process and restricting or changing the allocating directions by interactive operation. CONSTITUTION: Division control data for generating a shape model to be analyzed and a mesh are inputted through a keyboard 101b, a recognition model allocating respective segments to respective coordinate axis directions of an orthgonal coordinate system is equal to the connection relation of the segments is generated by a recognition model generating part 106 and a mapping model having an orthgonal grating on the surface or inside of the recognition model is generated by a mapping model generating part 108. The allocating directions of respective segments determined at the time of generating the recognition model from the shape model are displayed on the screen of a CRT display 101a together with values expressing the allocating directions of respective segments by respective colors and the restriction of the allocating directions by system user's interactive operation can be changed.
