Hi every formers:

I know If I am using low RE, then (nu() + nut()) U.snGrad() computed at the wall yields satisfactory results.
But if on the other hand you are having high RE, then an assumption of a log-profile would give reasonable results.

But I can not find out which code work for the log-profile, where can I find the method for this situation? Could anyone explain it for me? Thank you!
