akashmpatil is on a distinguished road
I want to model a flow in which I know the mass flow rate, inlet pressure, inlet temperature but I do not know anything at the outlet. I am interested in finding the pressure and other properties at the outlet.
The flow is compressible and so I cannot use outflow boundary condition. Also, I don't know the outlet pressure but the pressure outlet dialogue box prompts me to enter the outlet pressure which I don't know.
