MESH CREATION DEVICE, MESH CREATION METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce analysis time for analyzing a physical quantity of a material having a defect by a finite element method without deteriorating an accuracy of an analysis result. ! SOLUTION: When a cube is placed in a material such that the center of a defect corresponds to one of vertices of the cube, an area obtained by excluding an area occupied by the defect from a cube area is set as a mesh setting area 200. The cube utilized for the mesh setting area 200 is equally divided into three quadrangular pyramids that shares one of vertices of the cube. When the defect is placed such that the center of the defect corresponds to the vertex of one of the quadrangular pyramids, an area obtained by excluding the area occupied by the defect is selected from the mesh setting area 200 and set as a divided mesh setting area 210. The lengths of respective meshes in normal direction of the bottom surface of the divided mesh setting area 210 are set so as to increase in geometric progression in such a wa
