void	FD_Flux (const State_1D *state, int beg, int end, double *cmax, Grid *grid)

Detailed Description

The function FD_Flux() computes a high-order approximation to the flux divergence using WENO or Monotonicity-preserving reconstruction in characteristic variables.

It is called as a regular Riemann solver function except that the left and right states do not need to be defined since high-order reconstruction is done on the characteristic projection of the cell-centered fluxes.
