Hi All

I am doing a simple 3D nozzle simulation and I have an operating pressure condition which I wanted to give as my BC'n for inlet, so Inlet Pressure is 10 bar and the outlet is atm pressure 1 bar. But the simulation is not converging or the vectors are in the opposite direction and the Residuals are showing Reversed Flow !! Is is possible to give both Pressure as BC'n ? I am giving it as Stagnation inlet BC'n with constant pressure !! And outlet pressure as 1 bar. Kindly give me some suggestions or correct me if I am wrong.
Thanks in advance !!

I refer you to this thread on researchgate and for you to search this question on the forum. I believe it has been discussed before.
