Default non-zero mean velocity at wall surfaces

nenazarian is on a distinguished road

I was wondering if anyone else has observed a non-zero "mean" velocity at wall boundary conditions in fluent, while instantaneous velocity is always zero due to the no slip boundary condition.

I am currently using Ansys fluent 14.5 and I've faced some time-averaging issues in fluent before too.

Your feedback would be appreciated.

Yes it there. Becuase you are observing values at the cell center not the wall it self
