Hi everyone,
I have an experimental setup inside a closed chamber. The air is injected to the chamber through nozels. There are four exhaust holes for venting chamber using a fan. Velocity induced by the fan at these four exhaust holes is known. So i need to use this known velocity at these holes. what is appropriate boundary condition for pressure at these exhaust holes. using simple fixedvalue (for velocity) and zeroGradinet (pressure) combination crashes with continuity error. Please guide.. Thanks Mehar

So, I am attaching my experimental setup, in case someone needs to see it.
I am using simpleFoam with SA model. The velocity caused by Fan at exhaust points 1-4 is known. Thank You! Regards Mehar
