Hi,

I work on a 3D mesh without bondary layer
at the inlet, I want to have U=0.05 m/s
and on the wall U=0

I integer the U profile with excel
It has to be U*S

This is my inlet face

16/25 points belong to the wall
and only 9/25 belong to the inlet

I tried to change the order of boundary conditions in case/0/U but without results.
