NEM::MSH::GmshInterface Class Reference

management class for Gmsh interface More...

Detailed Description

Gmsh uses global (and static members) variables that are initialized and finalized by Gmsh API commands. This class manages geoMeshBase usage of Gmsh to guarantee finalization only when no geoMeshBase instances are left.
