1. An analysis model producing/assisting apparatus, comprising: a means for inputting a configuration model; a means for producing a recognition model, approximating surfaces of said configuration model and ridgelines thereof by planes and lines, respectively; a means for producing a mapping model of dividing said recognition model into cubic grids; and a means for producing an analysis model, forming hexahedron meshes through mapping grid points of the cubes of said mapping model onto said configuration model, wherein know-how for producing the analysis model, which gives an influence upon quality of said meshes of said analysis model, is take out from a database, and the taken-out know-how for producing the analysis model is applied onto said configuration model, thereby producing said recognition model.
