Hi all, I'm been working on trying to formulate a local DG scheme in deal.ii for a reaction-diffusion system. The general formulations in the examples for the time dependent cases though -- for example in step-33 -- are sort of CG based implicit solvers, while I want to build a local DG based explicit solver. Moving from the continuous to discontinuous elements seems fairly straight forward, but what has been causing me some severe problems is constructing a system explicitly (and locally) using the usual system_matrix formulation, or otherwise. My feeling is this should be fairly easy, but a few words of initial advice might go a long way at this point.
Many thanks, Evan
