摘要： PROBLEM TO BE SOLVED: To reduce a processing load of calculation in shape optimization.
SOLUTION: A shape optimization device 10 determines at first an initial value of ϕ corresponding to an initial shape Ω
0 (step S20). Then, the device 10 draws out a displacement u, a characteristic mode ϕ
k and a concomitant state p by a finite element method (step S21). A target function is drawn out followed thereto (step S22). A sensitivity of the target function is drawn out (step S23), a double well type potential f(ϕ) is drawn out, and reaction diffusion equation is solved by a finite volume method (step S24). The processing hereinbefore is repeated until the target function is converged.

摘要： PROBLEM TO BE SOLVED: To provide a finite element model analysis which can obtain a highly accurate analysis result with a relatively small calculation amount.SOLUTION: A structure analyzing device (10) comprises: a junction part determination unit (12) which determines a junction part at which a plurality of components are joined together in an analysis model representing an optional structure as an aggregate of a plurality of elements having predetermined displacement of component thickness direction at each node; an analysis model changing unit (14) which inserts an isoparametric element into the junction part, and also replaces the element at the junction part with a new element which is connected to the isoparametric element, has three nodes on axes crossing the junction part, and has displacement of each axis direction at each node that is approximated by a high-order function of a coordinate value on an axis of the component thickness direction, in order to generate a new analysis model; and a structure analysis unit (16) which performs structure analysis using the new analysis model.
