woodmark75 is on a distinguished road
Hi, I'm attempting to simulate a scaled model I have in a 'low speed' wind tunnel.

I've set up Fluent with; Inlet Velocity & Outlet Pressure. Outlet set to 0 Pa i.e gauge pressure. My query is what I should set the pressure to in 'reference Values'?

Should it be set to 1 atmosphere i.e. 101325 Pa? Also under; Define>Operating Conditions, should I include gravity? (Haven't seen this done in any tutorials). Thanks in advance...
