First, I'd like to thank the authors for the wonderful work they are doing !
Gmsh is one of the most useful free technical tools ever!
Thanks!
After this, I have a question.
It is possible to include in the .msh file a integer flag to each element ?
I need this to specify particular physical properties of the boundary.
Hi Umberto,
you should use Physical groups for that purpose, see
http://geuz.org/gmsh/doc/texinfo/gmsh.html#Elementary-vs-physical-entities
"Groups of elementary geometrical entities can also be defined and are called “physical” entities.
These physical entities cannot be modified by geometry commands: their only purpose is to assemble
elementary entities into larger groups, possibly modifying their orientation, so that they can be
referred to by the mesh module as single entities. As is the case with elementary entities, each
physical point, physical line, physical surface or physical volume must be assigned a unique
identification number. "

I'm the coordinator of the open-source project AcouSTO
http://acousto.sourceforge.net, a tool
for acoustic simulation. I'm going to release soon version 1.6 including the
possibility to read
Gmsh files.
Everything is working fine and the release candidate could be issued now, but
this additional
possibility
would broaden significantly the field of application.
Thanks in advance,
Umberto
