Hi all, I am doing a open domain analysis with Fan Moving Ref Frame. The Boundary Conditions are: 1.Inlet-Inflow -Stagnation Pressure 2.Outlet- Outflow -Static Pressure The outlet Geometry is such that the Backflow is possible. Whether the Outlet Boundary Condition I am giving is correct? Somebody advised me to extend the domain beyond the actual domain in order to correctly model the outlet flow. Otherwise Whether putting Inflow Boundary cond at oulet by putting Backflow ON will give me correct results? Anybody could give details about the (Inlet/Outlet) Bound COndns with different options and their effects on Results and oblige? Thanks.

these boundary condtions activation are varying from one code to another,. can you tell the code u r using?

I am using Acusolve, a Finite Element based Coupled Implicit Solver!
