[Gmsh] Error: No tetrahedra in region X

[Nick Barra]

Hi,

I am trying to create a hybrid mesh around a NACA2412 aerofoil to use in OpenFoam. When I use the 3D mesh option, I get the error that there are ‘No tetrahedra in region 7’. I have looked online and it appears to usually be solved by a missing surface in a surface loop, however, I can’t find which one I’m missing. I have attached the .geo file to this email, I would be grateful for your assistance.

Yours Faithfully,
Nick
