Mesh groups:

\(\mathrm{BAS}\): surface of the cube belonging to the \(Z=-0.5\) plane

\(\mathrm{HAUT}\): surface of the cube belonging to the \(Z=+0.5\) plane

\(\mathrm{DROITE}\): surface of the cube belonging to the \(Y=+0.5\) plane

\(\mathrm{GAUCHE}\): surface of the cube belonging to the \(Y=-0.5\) plane

\(\mathrm{DERRIERE}\): surface of the cube belonging to the \(X=-0.5\) plane

\(\mathrm{DEVANT}\): surface of the cube belonging to the \(X=+0.5\) plane
