[Gmsh] Gmsh produces meshes with different number of elements

[Octavio Castillo Reyes]

Dear all, thank you for your support and time.

Attached to this mail you will find the .geo file. Currently, I'm working
with gmsh-3.0.6 on a Linux system (64 bits). I used the GUI to load the
.geo and build the mesh.

Best regards

O.
