Abstract :
The BEM-FEM-coupling method has the advantage of the correct representation of infinite space. But there are also disadvantages. The system matrix is non-symmetric and it has a large mean bandwidth. We apply domain decomposition so that the original problem is split into a separate BEM and FEM part. The typical advantages of both methods are preserved so that reduced computer resources are needed. The solution of the overall problem is obtained by iteration. This paper deals only with eddy current problems
