Hi all!

I am trying to simulate 3D flow over a car. The problem is that the elements surrounding the contact patch between ground and wheel have a high skewness because they are very flat due to the inherent geometry of this contact patch. Is there any "meshing cheat" to solve this issue? I've tried to reduce the lenght side of the tetrahedrons to 1mm, but skewness is still about 0.999 in those elements.

Thanks a lot!

(I'm meshing with Gambit)
