Hi,

I'm using Fluent to analyze an airfoil. The airfoil is small and used in low velocity. Low Reynolds number and In-compressible flow. Since I'm using incompressible flow and I have uniform and fixed velocity I'm Velocity Inlet boundary condition.

All tutorials I have taken use Pressure Outlet. Why do they use Pressure Outlet?
