Benchmark 3D: The Compact Discontinuous Galerkin 2 Scheme

Conference paper
Part of the Springer Proceedings in Mathematics book series (PROM, volume 4)


In this paper we provide results for the 3d Benchmark on Anisotropic Diffusion Problems. We consider the Compact Discontinuous Galerkin 2 (CDG2) method first presented in [3]. In [3] a detailed stability analysis as well as a numerical investigation showing that the CDG2 method outperforms other DG methods (e.g. Bassi–Rebay 2, symmetric Interior Penalty, or the original Compact Discontinuous Galerkin Method, see [1, 3] and references therein) in terms of L2–accuracy versus computational time. Furthermore, the CDG2 method is a parameter free method in the sense that all tests have been calculated with the same set of parameters without specific test case tuning.
