Patent ID: 7730444

Claim:
A structural analysis method that is executed by a structural analysis device that performs a structural analysis of an analysis target that is formed from a plurality of materials with different physical properties, comprising: generating at the structural analysis device, upon dividing up the analysis target into a plurality of finite elements, element division data that associates positional information specifying a position of the finite element and material information specifying a material of the finite element, for each of the finite elements; defining at the structural analysis device a plurality of meshes that divide up the analysis target into units larger than the finite elements by means of positional information and calculating, for each mesh, a content rate of a conductor among the plurality of materials that occupy the finite element contained in the mesh on the basis of the element division data; substituting the material information in the mesh for the material information more than a prescribed ratio, if the content rate of the conductor in the mesh is more than the prescribed ratio; and calculating at the structural analysis device the physical amount yielded in the analysis target on the basis of the generated mesh data.
