v6.02.139 SSNL139 — Validation of the update of the girder twist angle

Summary:

When using beam elements with kinematics GROT_GDEP, the two nautical angles that reflect the orientation of the element must be updated at each iteration. The same goes for the 3rd nautical angle \(\gamma\) representing the angle of spin of the beam. The purpose of this test is to validate the re-actualization of this angle using a non-linear calculation.

It makes it possible to verify the modeling POU_D_TGM and that the models POU_D_E and POU_D_EM give the same results with the kinematics GROT_GDEP.
