Construct an unstructured tetrahedral 3D mesh making use of the free software gmsh.
The required argument geometry is the basename of the
*.geofile to be meshed.
The optional arguments option and value identify respectively a gmsh option and its value. For more information regarding the possible option to pass, refer to gmsh manual or gmsh site http://www.geuz.org/gmsh/.
The returned value mesh is a PDE-tool like mesh structure. If the function is called with two outputs gmsh_out is the verbose output of the gmsh subprocess.
