Electrical machines commonly consist of moving and stationary parts, e.g., an electric motor features a rotor and a stator. If volume based numerical schemes such as the Finite Element Method (FEM) are applied the electromagnetic simulation of such devices is a challenging task since the variation of the geometrical configuration needs to be incorporated into the numerical scheme. Contrary, a coupling scheme based on FEM together with Boundary Element Methods (BEM) neither hinges on re-meshing techniques nor deals with a special treatment of sliding interfaces. While the numerics are certainly more involved the reward is obvious: The modeling costs decrease and the application engineer is issued with an easy-to-use, versatile, and accurate simulation tool.
