Hi, I wrote a 2D Euler solver using finite volume, cell-centred scheme with Roe's FDS and Muscl iterpolation for left and right states. I have a problem in calculating the fluxes at wall boundaries. Can anybody give me any idea? Thanks in advance.... Regards.

One choice is just set Numerical flux on wall == original physical flux. This is essential in enclosed domian to ensure mass conservation.

Thanks versi. But what is physical flux? How is numerical flux set to physical flux? Regards
