Dear Salman,

I have also the same warning message in every run I do. I think that it has to do with the wall boundaries. Do you use standard wall boundaries for the standard k-e turbulence model? I think it has to do with the parameter y+ and u+ and the number of the cells we use to describe near wall treatment. I try to find out what maybe the problem is.

George.
