Abstract

In this paper, a parallel subdomain level discontinuous Galerkin time domain (DGTD) method is achieved via Message Passing Interface (MPI) library based on upwind flux and Runge-Kutta explicit time integration. A load balancing scheme is proposed for subdomains with multiple kinds of elements in different orders. Numerical examples demonstrate the effectiveness of the proposed scheme and good speedup is achieved.
