adudek is on a distinguished road

I am running a Fluent simulation of a 2D model of a car in a wind tunnel, using k-epsilon method.

I'd like to have all my y+ along the top side of the car the nearest to 30 to have the better precision. The "problem" is that the velocity is increasing along the windshield (flow section decreasing), the same for the y+ values.

My question is : is there a way to decrease the size/height of the boundary cells elements from the bottom to the top of the windshield ? (to remain the y+ at \approx value)

Thank's in advance
