[Gmsh] pb in a structured mesh?

[Cécile Giorla]

Hi,
When I mesh the cubic.geo file (see attachment) and mesh it (3D) and 
visualize the mesh elements (Tolls>Options>Mesh>Visibility>Volume faces 
on -but Surface faces off), we see some elements missing in the middle 
of the top of the box (see pictures).
Is this only a problem in the visualization? Or are the volume elements 
missing in the mesh?
Thank you.
Cecile Giorla.
