[Wedge]

Hi,

I have build a nozzle using the wedge method.
It also looks like it is supposed to.
But when I run the case and view it in paraview it looks like the wall boundary gets ignored.
I am not sure if it is a visualization problem or if also openfoam ignores it. It seems to happen everytime I use wedge for creating cases.
If I use a tinier grid at the wall the velocity goes down but it doesn reach zero.
Maybe someone of you knows this situation and can help.problem
