DGM provides a software framework for forward modeling and optimization of partial differential equations using the discontinuous Galerkin method (DGM).  Examples are provided for solution to generic Navier-Stokes (with and without subgrid-scale turbulence models), Euler, Burgers, Poisson, Helmholtz, Darcy, linear transport, and Advection Diffusion equations.

DGM supports a discontinuous Galerkin discretization in space using mixed nodal and modal representations with a variety of time advancement methods.  Includes modeling capabilities for boundary conditions, source terms, and material models with the ability to solve optimization problems for parameters describing each.  Also includes the ability to perform variational multiscale modeling for turbulence simulation.
