5. Summary of results

The results show the good modal behavior of the elements of the 3D_ FAISCEAU modeling in flexure, in the absence of the fluid. They also show a very good agreement of the frequencies of the ensemble modes with the heterogeneous Aster calculation, when there is fluid.

For the frequencies of the set modes, there are no differences between a HEXA8 and HEXA20 mesh (this is not true for the other modes).

The numerical results of the masses and inertias obtained by Code-Aster are very close to the analytical results (error \(\text{}<{6.10}^{-6}\)).
