Tested sizes and results
------------------------------

The aster calculation is performed using the DYNA_VIBRA operator on a modal basis containing the first mode of the structure without taking into account the static correction in order to be consistent with the assumptions of the reference calculations (ref. [:ref:`1 <1>`]).
