Abstract: A system for automatically dividing the form of an object to be analyzed using a finite element method, etc., into meshes, includes initial group generation means for generating a plurality of area division forms based on the form of the analysis object input through input means, and area division form evaluation means the generated area division forms. If the evaluation result does not satisfy a predetermined determination criterion, end determination means starts selection and crossover means for generating a new group and further starts mutation means for deforming the area division forms of the new group, then again starts the area division form evaluation means. If the evaluation result satisfies the predetermined determination criterion, an optimum area division form in the group is adopted as the optimum area division form. Division-into-meshes means subdivides the optimum area division form into meshes. The result of subdividing into the meshes is output to mesh output means.
