Functions

void HLLC_Solver (const Sweep *sweep, int beg, int end, double *cmax, Grid *grid)
 

Detailed Description

Solve the Riemann problem for the HD equations using the two-state HLLC solver by Toro.

On input, this function 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 i+1/2 (note that the i refers to i+1/2).

Also during this step, compute maximum wave propagation speed (cmax) for explicit time step computation.
