Boundary Layer Y+ Mesh Not Working as Expected

Hey,
I am using ICEM to generate quadrilateral and hexahedral grids for Airfoils and Wings. The flow Re number is 3 million. The corresponding first cell center height for a grid with y+ <1 is 8.5e-6m. Now earlier I have generated grids without any problem but for the recent work that I am doing I am not getting the grid spacing as I wish. A considerable number of cells from the airfoil wall have a constant thickness even though I have specified the grid growth ratio as 1.2. And the corresponding first cell height is less than required. I have attached pictures which will help explain the problem. Any help is appreciated. It is causing problems when I solve for the flow. Thanks https://drive.google.com/open?id=0B4...TdOMTZjdV8yalU https://drive.google.com/open?id=0B4...k5STUtILTRYakk https://drive.google.com/open?id=0B4...TdOMTZjdV8yalU |
