There are a number of packages available for generating Continuous Galerkin (CG) FEM meshes (gmsh, tetgen, netgen, etc.), but I have been unable to find one that generates Discontinuous Galerkin (DG) FEM meshes.
I'm currently interested in focusing on the solver part of DG, not the mesh construction, so a package that creates a simple DG quadrilateral/triangle mesh would be fine. I'm looking for an array of coordinates, node numbers, and element/node connectivity. Converting a CG mesh file (such as Gmsh) into a discontinuous one would also be fine.
Has this been done before - and if yes, what is available for personal use?
