Flux at wall boundaries for Roe's scheme

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

The original one. say, [ru, ruu+p, ruv, u(rE+p)]
