3D transient analysis of electromechanical devices using parallel BEM coupled to FEM

This paper describes the coupling of the parallel BEM to the FEM within the framework of a preconditioned iterative solver based on domain decomposition. This approach allows to overcome the limitations that arise on a serial computer when a 3D transient analysis of electromechanical devices should be performed. The parallel implementation of different BEM solution tasks is discussed. The numerical modeling of an electromechanical relay is presented as an example, including performance issues.
