Semi-analytical design sensitivity analysis of a coupled problem with a commercial finite element package

초록

This paper proposes an effective computational technique for design sensitivity analysis (DSA), the so-called displacement load method for semi-analytical design sensitivity analysis of coupled systems such as thermal-structure coupled system and electromagnetic-structure coupled system. Displacement load method evaluates the pseudo-load for DSA by using the difference of nodal forces that are related with design variables in a coupled system. This method is suitable for implementation of DSA outside a commercial finite element package. Several numerical examples are performed to verify the proposed method.
