Hello everyone!
I have a problem when i'm simulating an 2D uncompressible flow of the air above a flat plate.I need to obtain a u+=f(y+) law and compare it to the theory. The result that i have obtained (have a look at the image) does not look like the theoretical one as you can see on the image. The blue plot correspond to the result that I have obtained.

I used simpleFoam solver (openFOam1.7.1). The numerical schemes used are listed in the image attached to the post.
I think that the problem may be in the not sufficiently refined mesh close to the plate, or in the numerical schemes used.
If someone have an idea where the problem could be thank you for your indications .
