Discontinuous Galerkin methods in general relativistic neutron star simulations — •Marcus Bugner, David Hilditch, Hannes Rüter, and Bernd Brügmann — Theoretical Physics Institute, University of Jena, 07743 Jena, Germany

After the successful combination of Discontinuous Galerkin (DG) and pseudo-spectral methods for matter plus spacetime simulations, we present further extensions of our method. Targeting a reliable high-order algorithm, we put special focus on our shock capturing method and show the latest convergence results for fully general relativistic systems. Furthermore, we investigate the scalability of our numerical implementation.
