A Parallel and Non-Conformal Interior Penalty Discontinuous Galerkin Method for the Time-Domain Maxwell's Equations

摘要

In this article a parallel and non-conformal Interior Penalty Discontinuous Galerkin (IPDG) method is presented to solve time domain Maxwell's equations. The computational domain is decomposed into non-overlapping sub-domains. Each sub-domain is meshed independently providing great flexibility in the meshing process. Moreover a MPI parallelization along with a local time-stepping strategy is applied to significantly increase the efficiency of the method.
