Management system and management method of CAD data

Abstract

A management system of CAD data is provided, which stores sets of the CAD data, and a set of mesh conditions under which a CAE model is created from each of the sets of the CAD data and a set of analysis conditions under which CAE analysis on the created CAE model is performed associated with each set of the CAD data. Moreover, the management system of CAD data, to perform the CAE analysis on one of the sets of the CAD data, reads from the storage unit the set of the CAD data, and the set of the mesh conditions and the set of the analysis conditions associated with the set of the CAD data, creates the CAE model from the set of the CAD data under the read set of the mesh conditions, and perform the CAE analysis on the created CAE model under the read set of the analysis conditions.
