Default Combined Boundary Condition
Posts: n/a

I need to impose a mass flow rate at certain pressure as a boundary condition, how can I combine these 2 conditions in one of my boundaries? is not just the pressure inlet or the velocity inlet, what I want to have is a certain amount of mass coming thru a wall at an specified pressure.

thanks for your help

when u apply massflow inlet boundary condition, static pressure input is the requirment in the window. without pressure input mass flow boundary condtion is not fully defined

with regards

if its a compressible flow, just by giving the total and stagnation pressures, u can get this. Otherwise, I also dont know.
