PROBLEM TO BE SOLVED: To simplify an analysis object model while maintaining analysis accuracy. SOLUTION: The mesh of an orthogonal-line lattice applied at the time when the characteristics of an electrical appliance are subjected to a simulation analysis by using a plurality of kinds of attributes information including the coordinates information of a plurality of objects by using a model including the respective objects corresponding respectively to a plurality of parts constituting the electrical appliance, is processed in the following procedures. Namely, a heat flux is calculated as importance in the respective simulation analyses of the plurality of objects by using the attributes information (S13). Objects having low importance are removed from the object of the simulation analysis in turn while an inputted threshold (S11) is not satisfied (S15 and S16). As a result, a mesh for an analysis is set on the basis of the coordinates information of other objects except the removed objects (S17).
