grid refinement problem fluent 6
 
1 Attachment(s)
hello,

I'm using Fluent 6 with a mesh generated in Gambit. I'm simulating an NACA airfoil with the standard k-epsilon model. I've done some calculations but my results ain't good.

I made a XY plot of the y+ values. I read the the y+ must be bigger than 30.

When I want to refine the grid (adapt -> y+/y*-> mark for refinement. None of the cells are marked, only a few coarsened.

What can I do make my mesh/simulation correct?

Thanks in advance!!

Koen
