speicfying massflow rate at inlet with pressure

arun1994 · October 12, 2019, 10:28

Hello!

I would like to simulate a test section in a windtunnel at 10 bars of pressure in Starccm+. The boundary conditions are

Inlet : 10 Bar pressure , 200g/s through intlet
Outlet: 10Bar

ofcourse, the velocity at the intlet is not the same for 200g/s for 1Bar pressure and 10 bar pressure. I would like to know how I can specify the boundary conditions at the inlet.

It was a very stupid question. I just had to set reference pressure to 10bars and its ok.
