Limitations (for the moment) : macro domain must be parallelogram /  parallelepiped with axes aligned with cell periodicity directions; no offset between the origins of the RVE and part coordinate systems.
Test, only for 2D geometry, and demo for pantograph (generate mesh, full scale solving, homogenization then comparison);
+ Black;
+ Activate/Deactivate physical group visibility in gmsh model;
+ Function for mesh conversion .msh -> .xmdf or .xml.
