An analysis mesh is divided into closed areas which are stored combined with attribute information on physical properties and meshes as a partial area in a partial area registration step. A total area is defined in a total area registration step, and the shape of a partial area is changed in a partial area changing step. The arrangement is changed in a partial area moving step, then an analysis model is constructed by combining the partial areas and the total area in an area merging step. Finally mesh division is performed. Even in the case where there is an analysis mesh but no source 3D-CAD model remains, the present invention can easily modify a shape and efficiently create an analysis mesh. |
