I have a 3-d, viscous case with inlet mach no.=2.5. I am using pressure inlet BC at inlet and specifying gauge pressure, total pressure, total temperature at inlet. My outlet is supersonic outlet (some region near wall might be subsonic due to boundary layer formation). I am giving pressure outlet BC at outlet as in manual it says if flow is supersonic, it will automatically extrapolate values from interior rather than using back pressure values specified in pressure outlet BC.


I am not sure whether this is the right way to do it. Can anyone please confirm?
Also, I am getting reversed flow in many cells and not getting the solution. I am not sure whether it is because of this or any other issue. Please guide me in it.
