Slip Wall Function on Parallel Plates Gives Different Results

Hi folks,

I am trying to implement a No-Slip Wall Function in a K-Epsilon Turbulence Model on parallel plates.

I don't want to use a Low Re K-Epsilon Model from COMSOL.

So I impose a Slip Wall Function on both plates and use a pointwise constraint to make the velocity zero
at the plates.

However I get different results on each plate!!

I have tried to implement a friction velocity and impose the zero velocity for each plate separately amongst other
attempts but to no avail...

Can anyone provide some insight or info into this matter?

Best Regards,

Rui Silva
