Of course it is, but I compared the results with some other and the result of RANS matched in all cases the DNS-data and the wall function. So I think my results should do the same. I my thinking...

I have 2 nodes in z-direction, i wanted to do it with only one but ICEM automatically reset it to 2 nodes. Could this be a problem? It should be only a 2-dimensional simulation. No i didn't use...
