A novel DGTD method and engineering applications

Discontinuous Galerkin time domain (DGTD) offers attractive properties when it is applied to solve Maxwell's equations. The DGTD method is originated from the finite volume time domain (FVTD) and finite element method (FEM), and has the advantages of the two methods; furthermore, it is more flexible and accurate, and provides an embarrassingly parallel characteristic than FVTD and FEM. In this chapter, we introduce the basic concept of parallel DGTD method based on message passing interface (MPI) and graphics processing unit (GPU) based thread and memory access coalesced. The parallel DGTD method is then applied to solve the typical engineering problems. The numerical results demonstrate that the DGTD method is accurate and efficient for general electromagnetic problems.
