Dear all,

I am doing a study of the flow around truncated 2D airfoils using o-meshes and I would like to know if you know any reference where it is explained how to distribute the cells over the airfoil (i.e--> the amount of cells in the chordwise, trailing edge and leadign edge). I have been doing 2 different meshes with different distributions and I get a difference in the lift of 5%. It is not a lot, and the results look very similar to the reference I am comparing them to. However, I want to make sure I am meshing properly.
Maybe you can give me some advices or some references (papers...) where they talk about this.

Thanks,

José
