Displacement ug:


* known on the external nodes of substructures,


* it is assumed to be radial (with respect to O).


* u2 = DEPL_INTERNE (DEPL_GLOBAL = ug, SUPER_MAILLE = S2)

Displacement u2:


* known on all the nodes of ma,


* it remains radial because the field has been rotated by - 45° to be consistent with the mesh.
