Cube - mesh saving
Hi Not sure that it is an important bug, but ... I am using 2.8.3 version.
Take Cube.geo provided in the demos. As it is, no problem, the mesh with the 3D elements is saved.
Add : Physical Surface (10)={6} ; before the extrude command. Only that surface is saved... and not all other elements. If the surface numbers are known, one could create a physical volume. Since the numbering of the surfaces is unclear (at least for me), I do not know how to create this volume (without using GUI and return to the file). Something more practical would be welcome. However, congratulations for this excellent work. Philippe
