Mesh problem at the boundary layer
 

Dear all,

I'm modelling an intake and because a good turbulence model for this results to be the SST I need to refine the boundary layer. At the moment the boundary layer I got has y+ about 1000. If in ICEM I try to refine more at the boundary layer when I try to export the mesh, there are errors because in some points the mesh is distorted.
Do you have any suggestion about that?

Cheers and thank in advance!
