Catalin - the 3D algorithm is not very robust when you specify
characteristic lengths that are larger than the "size" of the
geometrical entities you want to mesh.

Try for example:

gmsh code1.geo -clscale 0.4
gmsh code2.geo -clscale 0.4

This multiplies all the characteritic lengths in your model by 0.4.
You can of course also directly modify your point definitions, use the
"Mesh.CharacteristicLengthFactor" option, or change the option in the
GUI (Tools:Options:Mesh:General:Characteristic length factor).

Cheers,

Christophe
