Paper on a DG Trefftz Method in Time-Domain

Fritz Kretzschmar, Igor Tsukerman and started working on a novel DG method using a Trefftz-type basis in time-domain. The method is formulated in a space-time FE setting and provides high order approximations in both, space and time, where the high order accuracy in time comes at no extra costs in terms in degrees of freedom. We demonstrated spectral convergence over the full space-time domain.

CEM Group at the SCEE Conference

Fritz Kretzschmar and myself will attend the SCEE conference in Zurich, Switzerland, September 11 – 14, 2012. Fritz will present his work on a novel Discontinuous Galerkin Trefftz-type method for time-domain electromagnetics simulations. I was given the change to contribute with a keynote talk and will summarize my efforts regarding dynamic hp-adaptivity for the Discontinuous Galerkin method.
