This paper describes the coupling of the parallel BEM to the FEM within the
framework of a preconditioned iterative solver based on domain decompositi
on. 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 i
s discussed. The numerical modeling of an electromechanical relay is presen
ted as an ex-ample, including performance issues.
