摘要: An efficient parallel algorithm for solving linear and nonlinear exterior boundary value problems arising, e.g., in magnetostatics is presented. It based upon the domaindecomposition-(DD)-coupling of Finite Element Galerkin Boundary Methods which results a unified variational formulation. In this way, magnetic field an unbounded domain with Sommerfeld's radiation condition can be modelled correctly. The problem nonsymmetric system matrix due to Galerkin-BEM overcome by transforming it into symmetric but indefinite applying Bramble/Pasciak's CG systems. For preconditioning, main ideas recent DD research are being applied. Test computations on multiprocessor were performed two practical interest including example.
