Abstract
We are dealing with a standard direct boundary element method and herein
with the collocation method. Our 3D BEM software package enables the
stress analysis of three-dimensional bodies under generalized body forces like
gravity, centrifugal force or arbitrary stationary thermal load. We have also
implemented the BEM specific symmetry option, where symmetry planes
do not have to be discretised. In this paper we focus our interest on the
iterative solution of the linear system of equations arising for symmetric
problems. We examine the convergence behaviour of the GMRES, the CGS
and the BICGSTAB algorithm for problems which are loaded by above men-
tioned phenomena.
