PROBLEM TO BE SOLVED: To deform a mold CAD model correspondingly to fine correction of a mold. SOLUTION: An FEM mesh model creation unit 14 creates a mesh model indicating elements and nodes of a finite element method corresponding to a surface of the mold CAD model. An intersection point calculation unit 19 calculates a displacement vector of a first node of the mesh model corresponding to an area wherein a measurement point is present in measurement data based on the measurement data of the mold created based on the mold CAD model and finely corrected, and the mesh model. A dynamic deformation solver 15 deforms the mesh model based on the displacement vector, and information related to a material press-molded by the mold created by the mold CAD model. A CAD model deformation unit 16 deforms a base surface constituting the mold CAD model based on the nodes of the mesh model, and displacement of the nodes before and after the deformation of the mesh model, and generates the mold CAD model after the deformation.
