PROBLEM TO BE SOLVED: To provide a device and a system which efficiently and sharply generate the best phase shape for a structure. SOLUTION: In a data generation stage S21, macroscopically averaged stress- strain matrix data are generated by applying a homogenizing method to a plurality of microscopic structures having internal sides of different length or the same length. In a 1st computation stage, stress-strain matrix data generated by using a plurality of representative internal-side lengths are interpolated S31 according to the lengths of the respective internal sides to compute a stress- strain matrix after coordinate conversion S32 of respective elements along the main axis. In a 2nd computation stage S40, finite element analysis is taken by using the stress-strain matrix computed in the 1st computation stage to compute a target function and the sensitivity of the target function and in a convergence decision stage S50, the relation between the target function computed by the finite element analysis and a predetermined threshold is estimated to decide convergence.
