Abstract: An analysis model creation assistance device comprises a mesh data registration unit for registering a mesh data which has been already divided into meshes for a simulation in a mesh database, a CAD data registration unit for registering a CAD data corresponding to the mesh data in a CAD database, and a usable mode extractor for registering a mesh data corresponding to a data on mesh members excluding a mesh member of a largest size in a usable model database as a usable mesh.

Abstract: A modeling support system stores a combination of a CAD model and a mesh model corresponding to the CAD model; recognizes a shape indicated by the CAD model; and classifies respective parts of the stored CAD model into one of a plurality of groups. The modeling support system also specifies component parts of an input CAD model and specifies groups corresponding to the specified component parts from the specified groups. A similar-shape-model search unit searches and obtains the part of the CAD model having a shape most similar to the shape indicated by the specified component part, from the part of the CAD model in the specified groups. Further, a mesh model generating unit obtains a mesh model corresponding to the obtained part of the CAD model, from the stored mesh model, and generates a new mesh model.
