Modeling
 

Hi,

I have a geometry with a 'main' inlet and two 'side' inlets, an outlet and 2 vents. The 'main' inlet is held at a pressure of 1000 Pa. The two 'side' inlets are at pressure of P1 and P2. The vents are open to atmosphere. I want to plot my outlet pressure vs P1 and P2. But I know nothing about my outlet BCs. I couldn't calculate the mass flow rate through my outlet because of the complicated geometry. Can anyone help me with this issue?

And I also don't understand if I have applied a pressure of 1000 Pa, but I observed pressures of upto 10^5 Pa in post-processing. And some negative presure values also. Can anyone explain to me what does that mean or why is that so?

Thanks, Ruchi

Did you specify pressure values with respect to default reference pressure of 1 atm?
