[Gmsh] how to define surface properties in gmsh input files?

[Ruth V. Sabariego]

The material description is not done in Gmsh.
Nevertheless, you can define "Physical Regions" and use them in your 
computation software.
That way, you will have a tag in the mesh file (see manual) that allows 
you to identify the elements belonging to those physical regions. You 
can thus associate material characteristics, boundary conditions, and so 
on.

For instance:
Physical Volume (Your_tag1) = {geo_volume_number};
Physical Surface(Your_tag2) = {geo_surface_number};
Physical Line(Your_tag3) = {geo_line_number};
Physical Point(Your_tag4) = {geo_point_number};

Regards,
Ruth
