Savegmsh ? seems not to work

General Discussion
1

Hello all !

I was asked by a collegue to export a mesh generated by FreeFem++ in a format readable by Fenics.
I first thought about using gmsh format.
There is a command “savegmsh” documented in the manual but it does not seem to work
(see below the log for a basic example).

Any hope for this to work ? or any suggestion about other format we could use ?

Thanks
David

It does not work for 2D meshes.
