Abstract: 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.

Abstract: An analysis model producing apparatus uses CAD data and part-unit analyzing mesh data therein. The CAD data has parts CAD data for each of parts of an assembly and disposed position data for each part, and in addition thereto, a modeling kind on a connect-portion between the parts and connect-portion modeling data for presenting a modeling method.
