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?
Define a (or more) Physical Volume(s). Then Gmsh will only save the
volume elements belonging to those.
