The Dune FEM module: Discontinuous Galerkin for evolution equations

DUNE-FEM-DG

DUNE-FEM-DG is the implementation of Discontinuous Galerkin schemes using the DUNE-FEM framework. Stabilized DG schemes for hyperbolic as well as a wide range of different primal formulations for elliptic/parabolic problems are implemented. The operators can be used efficiently both in a explicit/matrix free implementation or used to setup a system matrix for use with the linear solvers available in DUNE-FEM.
