Sure: just create a post-processing view containing scalar or vector
lines representing the edges in the grain boundaries. It might be a bit
of an overkill (since you might have no use for the data associated
with the lines) but it's fairly general, as you can then use all
the usual transformation tools on these lines (i.e., to apply offsets,
deformations, etc.).

Note that Gmsh currently does not support 6-node triangles in the
post-processing views. You will have to subdivide your triangles before
writing the post-processing files.
