Good evening,

I am trying to solve a conjugate heat transfer problem through a simple electronics device case. The case geometry is a simple box with 4 rounded shaped holes. 2 fans are blowing air into the case where as the other 2 holes on the other side of the case function as outlets. How do I setup the boundary conditions for this setup? I do know the mass flow rate and pressure the fans are operating at. The gas is air.

Is there a possibility to apply both pressure and mass flow rate at the inlet?
For the outlet I think I dont need any BC then

Thank you very much for your time.
