**Results from** MACR_LIGN_COUP on the AB segment:

The NON_REGRESSIONsont tests done on the tables from MACR_LIGN_COUP applied to a CHAMP_GD. They are the 'AUTRE_ASTER' reference values for tables from MACR_LIGN_COUP applied to a mult_elas result.

notes
---------

Modeling in HEXA20 is completely acceptable for this rough meshing. This modeling also makes it possible to test whether the application of gravity to a list of cells or groups of cells is properly taken into account.
