Is there any software or source code of Discontinuous

In applied mathematics, discontinuous Galerkin methods (DG methods) form a class of numerical methods for solving differential equations. They combine features of the finite element and the finite volume framework and have been successfully applied to hyperbolic, elliptic, parabolic and mixed form problems arising from a wide range of applications. DG methods have in particular received considerable interest for problems with a dominant first-order part, e.g. in electrodynamics, fluid … WeblibMesh currently supports 1D, 2D, and 3D steady and transient simulations on a variety of popular geometric and finite element types.
