Hi All I am continuously receiving the following warning, ispite of the fact that the convergence criteria is always achieved. So please tell me about this warning and how to overcome it. Thanx Salman

"*** WARNING #090 *** VALUE ELOG*YPLUS OR ELOG*EFFVIS/(CAPPA*VISCOS) IS LESS THAN 1.1 AT 832 CELLS. UPLUS=YPLUS LAW IS USED. IF THIS SITUATION PERSISTS, INCORRECT RESULTS MAY BE OBTAINED."

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.
