PURPOSE:To reduce the operation quantity of program generation by inputting a shape, property values, and load data regarding a structure, performing Taylor expansion by four operating as to the processing result of a finite element method circuit, and inputting the result to a perturbation method circuit and finding and displaying a secondary differential coefficient. CONSTITUTION:The shape, property values, and load data regarding the structure are inputted to an input device I and processed by the normal finite element method circuit II, whose processing result is processed by Taylor expansion III by four operations; and the result of the Taylor expansion is inputted to a perturbation method circuit V to find the secondary differential coefficient, which is displayed on a display device V. This is applicable to analyses of any element and static and characteristic values using numeral integration, and built in a processor for an existent finite element method program, and an error in mathematical expression expansion for the designing of a differentiating circuit is eliminated to improve the reliability of the program. Consequently, the operation quantity of program generation is reduced.
