hson is on a distinguished road
I have modeled a simple cylinder as a fluid ( Water mesh) in CFX. With the following boundary conditions:
Inlet: Normal velocity
Wall: no slip
Outlet: 0 Pressure
But strangely in post processing, when I measured velocity in the wall, it was not zero and in many sections, it was even more than average velocity in the section. It is strange because I have defined walls to be no slip. Could you please advise me to know the reason for this result?
