[Gmsh] Extruding a 2D Surface Created in FreeCAD

[James Gross]

Hi people,

I am hoping to use Gmsh to create a 2D mesh for OpenFOAM. I've created the
original 2D surface in FreeCAD and exported it as a BRep file.

When I try to extrude the surface, it doesn't work. There are no error
messages, but the surface hasn't been extruded. When I created the geometry
in Gmsh, there was no issue with extrusion.

Here is a shortened version of the script.

Merge "Part.brep";
>
> Recombine Surface{1};
>
> out[] = Extrude {0,0,1}
> {
>   Surface {1}; Layers{1}; Recombine;
> };
>
> Mesh.Smoothing = 100;
>

Thanks.

James
