FORM DIVIDING SYSTEM

PURPOSE:To improve the analysis precision by controlling a knowledge data base to determine a division system and not only converting a geometrical model data base to substructures but also dividing elements by the division system to generate a finite element model data base. CONSTITUTION:A knowledge data base 101 which consists of a form pattern data base 102 for form confirmation and a division system data base 103 having plural automatic division algorithms and a division control part 105 are provided, and this division control part 105 controls the knowledge data base 101 to determine the division system and not only converts a geometrical model data base 104 to substructures but also divides elements by the division system to generate a finite element model data base 107. Since elements are centralized and fractionized with respect to geometrical models, approximation error is not generated and finite element models of high precision are generated. Thus, the analysis precision is improved.
