[Gmsh] problem with gmsh 3D

[MENESGUEN Yves 200289]

Hello,
I am a new gmsh user and I need some help to mesh my parallelepiped. I need to mesh this volume to use with freefem3D. The structure I want to mesh is in the joined file. It is made of 5 thin parallelepipeds I need to mesh with ~10 points each one in the z-direction (the thinner) and 40 in the x direction and 80 points in the y-direction. 
Gmsh doesn't manage to mesh anything, and I don't understand what the fourth coordinate of the point do.
 
Best regards,
