4. Summary of results

In this test, only structure frequencies are tested; we are not interested in free surface frequencies.

The results obtained are in good agreement with those obtained by SAMCEF since the maximum difference with the reference solution reached :math:`7.5`%.

It should be noted that a relatively fine mesh was also used in order to obtain results close to the reference solution (5 meshes along the radius, 16 meshes along the height and 32 meshes along the circumference).
