Section: Software

Euler equations

Participants : Roland Becker, Robert Luce, Eric Schall, David Trujillo.

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, Steger-Warming, and HLL have been implemented for test problems. A typical example is the scram jet test case shown in Figure 8 .
