5. Summary of results

The results are satisfactory. The relative error corresponds to the numerical error associated with the integration of time. The initial conditions are well taken into account. It is concluded that Code_Aster correctly simulates a release in linear dynamics.

This test is also a functional validation of the recovery in the form of a function of the evolution over time of the participation of a mode, as well as a validation, in the case of a linear relationship, of the RELA_EFFO_VITE feature.
