Robust FEM/BEM Coupling for Magnetostatics on Multiconnected Domains

This paper presents a method for the computation of magnetostatic problems based on symmetric finite element/boundary element coupling. A reduced scalar magnetic potential is used in the unbounded air region for the boundary element method (BEM). The magnetic vector potential is only used for the finite element method (FEM) inside the bodies. The advantage and novelty of the presented method is the robustness with respect to magnetic materials in combination with the possibility to treat multiconnected domains.
