PROBLEM TO BE SOLVED: To reduce the preparation man-hours of a geometric model in a method for designing a construct including structure elements for performing mechanism motion based on the analysis result of various geometric models. SOLUTION: Mapping models divided into finite elements are prepared based on the basic shape of a crankshaft. Those mapping models are assembled, and deformed into a shape geometrically equal to a geometric model while their topologically equal shapes are maintained, so that a basic model 76 is prepared. Also, the geometric model is prepared by changing the dimension of a portion of the basic shape, and the mapping model is deformed into a shape geometrically equal to the the deformed geometric model, so that a deformed model 78 is prepared. The mapping model is shared, so that it is possible to succeed the numbers of respective elements divided into finite elements of the basic model and the deformed model. The numbers of the elements to be specified for mechanism motion analysis designated by the basic model 76 are succeeded to the deformed model 78, so that it is not necessary to re-designate the numbers.
