PROBLEM TO BE SOLVED: To provide a mesh generation method capable of preventing reduction of calculation accuracy in numerical simulation even if a defect is present in three-dimensional shape data, or even if a minute face is present among faces constituting a shape surface. SOLUTION: A surface mesh constituting a closed space is generated on the surface of a three-dimensional shape. When a gap is present between the face and the face constituting the shape surface when generating a three-dimensional mesh in the closed space configured by the generated surface mesh, the surface mesh is generated such that the mesh shares a node in a boundary of the face and the face apart from it within a tolerance, that is, on a side constituting the face. When the faces overlap within the tolerance, the surface mesh is generated such that the nodes and the meshes become equal on the overlapping faces. COPYRIGHT: (C)2006,JPO&NCIPI
