A parallel full geometric multigrid solver for time harmonic Maxwell problems
This paper is concerned with the solving of complex linear systems of 3D time harmonic Maxwell-type. This is done by implementing a parallel full geometric multigrid solver with a matrix-free smoother and a robust parallel direct solver on the coarse mesh. The final part of this paper illustrates the numerical robustness of the proposed scheme.
