GMSH2OGS; extract boundary meshes

Dmitry Yu. Naumov requested to merge endJunction/ogs:Gmsh2OgsExtractBoundary into master

Adding a new command line flag '-b' to GMSH2OGS. With the flag being set, the line elements (same as those removed by the '-e' flag) are extracted as individual meshes. The new meshes are stored in files corresponding to the material ids.

  1. Feature description was added to the changelog
  2. Tests covering your feature were added?
  3. Any new feature or behavior change was documented?

In the following figure:

  • the lower mesh is produced with GMSH2OGS -i gmsh.msh -o x.vtu with 8 materials,
  • removing the line elements gives the second lower mesh GMSH2OGS -i gmsh.msh -o x.vtu -e with just two materials,
  • extracting the boundaries will produce the line meshes GMSH2OGS -i gmsh.msh -o x.vtu -b: there are 8 meshes, one for each material. (For visualization purposes the meshes are translated.)
