[Gmsh] MSH Format

[Ted Kord]

This may be a naive question but humour me.

I've meshed my geometry using Gmsh  and the mesh file has the usual format.
In the $Elements section, there's connectivity for triangles and tetrahedra.
Am I correct in saying that:

a) the triangles are surface/boundary elements and

b) I can ignore the triangles (if for the moment, I'm not concerned with
boundary conditions, etc) and only use the connectivity information for the
tetrahedra and still have the mesh and its nodes correctly represented?

If the answers to these are 'NO', is there a way for me to generate a mesh
with only nodes and connectivity information for tetrahedral elements only?
