| Freeslip Wall Flux Boundary Condition This boundary condition is meant to set the boundary condition on a freesslip wall for 5-Moment This just sets the local x momentum flux to the presssure This isn't really correct as it is not the solution to the Riemann problem in which the velocity is supposed to flip signs from left to right, so really you need to solve the Riemann problem properly (which will depend on weather you get 2 shocks, 2 rarefaction waves, or some other combination) or put in the soluition of a approximate Riemann Solve directly.
