Abstract

This paper presents the parallel implementation of the BEM analysis with the domain decomposition method (DDM). The domain under considera- tion is decomposed by virtual internal boundaries. Boundary conditions on internal boundaries are assumed and then, the BEM analyses of the sub- domains are performed in parallel. The assumed conditions are modified according to the numerical results and the process returns to the paral- lel computation. The Uzawa's and the Schwarz' methods without domain overlap are applied as alternation schemes on the internal boudnary. The present method is applied to the two-dimensional potential problem in order to discuss their convergency properties. 1 Introduction In the numerical analysis of a large-scale problem, there are two difficulties to b
