Abstract

A parallelizable unconditional stable discontinuous Galerkin finite element time-domain (DG-FETD) method is presented in the paper. The Crank-Nicolson (CN) scheme is implemented in DG-FETD method and it can eliminate the stability constraint from the minimum size of meshes. A causal domain decomposition technique is proposed to make the coupled system parallelizable. A numerical example is simulated to demonstrate the accuracy and efficiency of the proposed method.
