To easily and accurately perform optimum wiring design for a wiring structure in a short period of time without depending upon a designer's level of skill by sequentially calculating the shape of the wiring structure and outputting the results.
This wiring structure 1a constituted of a plurality of line streak members is considered as an elastic body in which a plurality of beam elements whose linearity is maintained on a circular cross section are coupled with each other. A finite element method is used to output a predicted shape of the wiring structure satisfying a predetermined condition. Particularly, The aspects of deformation of the wiring structure, when an initial shape of the wiring structure is changed to the balanced final shape 1z of the wiring structure, are sequentially calculated by using the finite element method while satisfying the shape characteristics, material characteristics and constraining condition of the wiring structure, and the results are sequentially outputted.
