PROBLEM TO BE SOLVED: To generate a large-scale analysis mesh of a scale from millions of elements to tens of millions of elements at high speed. SOLUTION: A triangular mesh generation portion 104 of a large-scale analysis mesh generation program 102 divides the surface of geometry model to be meshed in a meshed manner according to a target element dimension and generates a triangular mesh on the surface of geometry model. A regular mesh generation portion 105 assumes a shaped parallelepiped enclosing the shape to be meshed, divides the parallelepiped in a meshed manner by the hexahedral element whose distance between the nodes has the substantially same density as the triangular mesh on the surface to generate a regular mesh, and divides the regular mesh located inside the triangular mesh on the surface of geometry model into a tetrahedral meshed manner. A shell meshing area extracting portion 106 extracts a shell-like space between the inner tetrahedral mesh and the triangular mesh on the surface of geometry model. A shell mesh generation portion 107 generates the tetrahedral mesh in the overall shape to be meshed. COPYRIGHT: (C)2009,JPO&INPIT
