To fix the Boundary Condition values

JSM

Hai,

I am doing the simulation of cyclone separator. In this I am using the velocity inlet(20m/s) and pressure outlet(atm. pressure) boundary conditions.

But after the solution is converged, I checked the velocity and pressure. Inlet velocity is 15 m/s and outlet pressure is 600pascals more than atm. pressure. But I really want atmospheric pressure at outlet. How to give the boundary conditions to fix the atmospheric pressure at outlet.

Thanks in advance,

with regards JSM
