Two-shock Riemann solver for the HD equations.
More...
Solve the Riemann problem for the Euler equations of gasdynamics using the two-shock approximation.
- On input, it takes left and right primitive state vectors stateL->v and stateR->v at zone edge i+1/2; On output, return flux and pressure vectors at the same interface.
- Also, compute maximum wave propagation speed (cmax) for explicit time step computation
