Dear all,

I begin by thanking you for all the work on Gmsh, which is very impressive.

I generate a 3d mesh with the attached file .geo. I can load it with a
Finite Element solver named FreeFem++, but do not succeed to define periodic
finite elements space on my weird cube: I have the following error message

"the both number of face is not the same "

How can I fix this, and impose the same elements on the symmetric sides of
the cube ?

I thank you very much in advance for all piece of advise you could give me,

Best regards,
