Hello,

I am with some doubts about the boundary condition that I should select at pipe exit...I am simulating a pipe flow, the flow is like a closed circuit type and I'm interested in a section of 4m where the flow is developed. I have used an Outlet boundary type "Pressure, no viscous stress", a colleague mine chose "normal stress,normal flow" in Boundary stress.
Someone can give me more information?
