How to create a 2D Gmsh boundary layer?
 

Hi

I'm trying to create a boundary layer over RAE2822 airfoil and from what I've seen from the previous posts, most of the people have used extrude command to do that as they've been using OpenFoam as the solver.

But I'm using SU2 as the solver and I don't need to do that. So, is there a way to specify a boundary layer region around the airfoil without using extrude command and converting it to 3D?

Any help would be appreciated.

Thanks
