Abstract
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. The present invention divides the analysis mesh into closed areas in a division step and stores the closed areas combined with attribute information on physical properties and meshes as a partial area in a partial area registration step, defines a total area in a total area registration step, changes the shape of a partial area desired to be changed in a partial area changing step, changes an arrangement in a partial area moving step, then constructs an analysis model by combining the partial areas and the total area in an area merging step and finally performs mesh division in a mesh division step.

An analysis mesh creation method comprising:
- a division step of dividing an analysis mesh into a plurality of closed areas having information on a shape and a position;
- a partial area registration step of storing the closed areas combined with attribute information on physical properties and meshes as a partial area;
- a total area registration step of storing a total area which is an area combining all the partial areas and having attribute information on the specific partial area;
- a partial area changing step of changing the partial area desired to be changed;
- a partial area moving step of optionally changing a position of the partial area;
- an area merging step of constructing a new analysis model by combining the total area and the at least one partial area using the position information;
- and
- mesh division step of performing mesh division on the constructed analysis model and thereby creating a new analysis mesh.
