Dear gmsh users,

I am generating a mesh with gmsh (geo file attached) and I get a freefem
readable  mesh (freefem_mesh.msh also attached)

but it seems I have trouble reading the mesh :

here is the error I get :

 ## Warning: Mesh without geometry we construct a geometry (theta =-57.2958
degres )
+++  Fatal Error Triangle (in SetInCoor) area of Triangle < 0

Do you see an obious problem with my file ? (I don't really understand
because I generated in the past the same kind of mesh and it was fine ...)

thanks a lot for your help!
