Abstract
For an efficient coupling between domains, treated by the Finite Element Method (FEM) and those, treated by the Boundary Element Method (BEM) it is desirable to have symmetric formulations of both [1]. The collocation as well as the Galerkin approach lead to nonsymmetric BE matrices [2, 3]. The symmetric Bubnov-Galerkin BEM [1, 4] requires the treatment of hypersingular kernels and a high computational effort for double integration of the spatial shape functions.
