One for hot fluid and another is cold fluid. Each inlet has its own mass flow rate and pressure. I use mass flow inlet BC to input the mass flow rate, but I don't know where to input the pressure since the Fluent help said that the value of supersonic/initial gauge pressure is neglected if the condition is in subsonic. My question is what BC I have to use for this condition, especially for the inlet and the outlet. Thank you
