Abstract :
The discontinuous Galerkin time-domain (DGTD) methods are promising in transient analysis of large and multiscale problems. Based on the idea of domain decomposition, the DG method can handle problems too large to be solved by conventional numerical techniques. Basically, the DG method divides an original problem into several well designed subdomains, i.e., split a large system matrix into several smaller and balanced matrices. Thus, once the spatial discretization is defined, an optimal time integration method is crucial.
