摘      要：Discontinuous Galerkin(DG) method has been successfully used in time dependent simulations. This paper will investigate DG solvers for di_erent simulations. They are compressible flow and electromagnetic wave simulations. The compressible flow simulation needs to solve the Euler equation, while electromagnetic wave simulation needs to solve the Maxwell s equations. Two solvers have been studied in deep separately. All solvers apply domain decomposition method for the parallelization, and they both show the advantages of DG method: easy parallelization and good scalability. Verifications will be shown on simple geometries in detail for both cases, and at last a wakefield simulation ha been shown with electromagnetic time domain solver.
