v5.02.103 SDNL103 - Dynamics of a gantry modelled by highly rotating beam elements. Comparison with a small rotation analysis

Summary:

We analyze the response of a gantry, embedded in feet and subjected to a dynamic force applied in the middle of its span and perpendicular to its plane. The trips are small. Two beam models are compared: POU_D_T_GD and POU_D_T.

Interest: test the highly rotating beam element MECA_POU_D_T_GD and the DYNA_NON_LINE control.
