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.

The boundary conditions are applied to the faces, not to the points. So think about what average velocity you want to go into a face.
