Parallel Waveform Relaxation and Matrix Solution for Large PEEC Model Problems

Excessive compute time is becoming a key problem for high performance system modeling as the complexity of the electromagnetic and circuit models is increasing. At the same time the PEEC models are locally becoming more complex with the increased importance of dielectric and skin-effect losses. In this paper, we consider a combined approach where waveform relaxation is used for the predominant weak coupling while a Gaussian matrix solver is used for the parallelization of the strongly coupled parts of the EM/Ckt solver.
