Analysis model generation program, analysis model generation apparatus, analysis model generating method, and method for manufacturing apparatus with analysis model generating method

An analysis model generation apparatus which generates an analysis model by processing a three-dimensional geometric model of an apparatus including a plurality of parts, comprising:

• a reception unit receiving the three-dimensional geometric model as input, and storing the three-dimensional geometric model in a first storage unit;
• a fastening portion extraction unit referring to a second storage unit storing attribute information about fastening between the parts, and extracting a fastening portion at which a first part and a second part are fastened based on the attribute information and the three-dimensional geometric model;
• a dividing unit dividing each of the first part and the second part into a first geometry in proximity of the fastening portion and one or more second geometries corresponding to a remaining portion of the first geometry in the three-dimensional geometric model;
• and
• an equivalent property value assignment unit operating with respect to each of the first geometry obtained by dividing the first part and the first geometry obtained by dividing the second part, wherein the operating includes referring to a third storage unit storing a parameter depending on the attribute information and a property value depending on a material of the part, calculating an equivalent property value as a property value reflecting fastening based on the parameter and the property value stored in the third storage unit, and assigning the equivalent property value to the first geometry, wherein the first geometry is assigned the property value different from the property value of the first part before the dividing.
