Hyperbolic solvers

Participants : Roland Becker, Robert Luce, Vincent Perrier, Eric Schall.

Based on the library Concha we have develop a solver for hyperbolic PDE's based on DGFEM. So far different standard solvers for the Euler equations such as Lax-Friedrichs, HLL, Steger-Worming,... have been implemented for test problems. The structure of the program permits rapid generalization to more complex models.
