hi I am simulating flow behind a bluff body. Not I know that if I want to use the wall function. the y+ plus values should not be less than 11 and greater than 60. How can I make delta x of the first node to the value which I require and use the structure grid i.e delta x in other cels are equal and less than delta x in the first cell.

just use "adapt -> Y+/Y*" in Fluent and let it adapt your mesh. However in 3D grids I have only been able to refine the grid (no coarsening)..
