A discontinuous Galerkin Method for Computing Flow in Porous Media

We consider a discontinuous Galerkin scheme for flow in heterogeneous media. An efficient solution of the resulting system of unknowns is possible by taking advantage of a priori knowledge of the direction of flow. By arranging the elements in a suitable sequence, the full system need not be assembled and one may compute the solution in an element by element fashion. We demonstrate this procedure on boundary-value problems for time of flight and tracer flow.
