[Gmsh] Problem with Reading the mesh generated into freefem.

[G. D. McBain]

Hi there. I'll look into this in more detail back in the office tomorrow, but just quickly, I'm very familiar with this error message. It means that the surface is not oriented consistently. Gmsh is always three-dimensional so it doesn't have an idea of clockwise, e.g.

The usual remedy is to change the sign on some of the curves defining the surfaces in Gmsh. Does that make sense in your application?
