Usually one defines the mesh vertices on the exterior faces and the mesh 
generator determines the location of the mesh vertices inside the 
rectangular.
Since I have no mesh generator, I simply created a 3D structured mesh 
and wrote the mesh in an unstructured format (tetrahedra, ... etc). Thus 
metis reads an unstructured mesh.

How do I tell metis to partition the mesh so that the partition 
boundaries are along x= constant lines?
Hope this helps.
Thanks,
