DGMat using deal.II finite element library. Generates Mass and Stiffness matrices for tensor-product elements in multiple space dims. Can be used for validation of in-house codes.
MEANDG- Mixed Element Applications with Nodal Discontinuous Galerkin methods. It is a 3D DG solver for Euler's and N-S equations. I have contributed to the central framework (design and development) of MEANDG.
