Abstract

This paper presents a new boundary-type scheme for the sensitivity analy- sis of three-dimensional potential problem by Trefftz formulation, which is formulated by the collocation method. Then, the shape sensitivity analy- sis scheme based on the collocation-Trefftz method is explained. The heat transfer on a thick-walled cylinder is considered as a numerical example in order to confirm the validity of the formulations. 1 Introduction Sensitivity analysis scheme is very significant technique for solving various inverse problems such as the shape optimization, the moving boundary prob- lem and so on. Therefore, many researchers already presented the sensitiv- ity analysis schemes based on the finite or the boundary element method. However, they have some dif
