Parallel computing for the combination method of BEM and FEM

A new algorithm for the parallel computing of the boundary-element and finite-element combination method is presented in this paper. By introducing the domain decomposition of an entire domain under consideration into the boundary-element and finite-element subdomains, each analysis is performed independently and in parallel. A renewal iterative scheme for parallel computing is the Schwarz method which was previously adopted to the domain decomposition parallel scheme in boundary-element analysis. A cluster parallel computing system by workstations connected by the LAN is constructed and employed aiming at efficient analysis. Convergence and accuracy of solutions on the internal virtual boundaries are shown through some sample examples.
