Static pressure boundary condition
 

Hello,

I am simulating a very basic wind tunnel. I have the mesh done and the solution has converged.

I have simulated it with pressure boundary condition. I know that the total pressure increase in the axial fan is 1500 Pa, so the outlet condition is a gauge pressure (static) of 0 Pa and the inlet condition is a gauge pressure (static) of 1500 Pa.
But I must give fluent the total gauge pressure (static+dinamic), What can I do it If I don´t know the velocity in the fan outlet?

Another problem I have is If I give a total gauge pressure (estimated), the static pressure in that section is non-uniform, but the fan gives an uniform pressure I think. Is this normal?

Thank you
