[Gmsh] Reversing 2D Boundary Layer Normal

[John Pease Moore]

Hi GMSH developers and users,

I've been trying to flip the element normals created in a 2D boundary layer generated using the "BoundaryLayer Field = " comand, but have not had any success. Is this possible? 

If the command created another entity (surface), I could reverse the normal with the a command like "Physical surface(2) = -{NewSurfaceID)". However, it does not appear that a new entity is created.

Any ideas?

Below is a simple script of a BL about an airfoil.

Any help would be greatly appreciated!

Thanks,
John
