FINITE ELEMENT GENERATOR AND METHOD FOR GENERATING FINITE ELEMENT

摘要

PURPOSE: To generate an even quadrilateral grid by controlling the number of grids in each plane forming a shape model in shell structure and applying curvilinear coordinate transforming method to each plane by means of a mapping model generated based on the number of assigned grids. ;CONSTITUTION: In each segment forming a shaping model generated by a shaping model generating part 9a, a number-of-assigned-grids setting part 9b controls the number of grids viewed from the entire shape model and sets the number of grids of each plane capable of grid division. Based on the number of assigned grids, a mapping model generation part 9c generates the mapping model of each plane. Based on the mapping model, a mesh generation part 9d internally generates grid points by applying the curvilinear coordinate transforming method to each plane.;COPYRIGHT: (C)1993,JPO&Japio
