Parallel field computation based on coupling of differential and integral methods

This paper deals with the coupling of a parallelized differential (FEM) and a parallelized integral approach (BEM) under control of a master process w ithin the framework of a preconditioned iterative solver Applying a domain decomposition scheme splits the problem into separate FEM and BEM parts pre serving the typical advantages of both methods Therefore an independent par allelization with respect to the special properties of both methods is poss ible. The limitations that arise on sequential computers when performing 3D transient analysis of nonlinear eddy current problems especially with moti on can be overcome with this approach. The parallel implementations are dis cussed with focus on a strategy that keeps substantial parts of the paralle lization separated from the numerical algorithm. The numerical modeling of an electromagnetic valve is presented as an example.
