*   Pour les tests 1 et 2, les quadrangles de la fiche NAFEMS ont été découpés en triangles.


*   Les tests 3 et 4 peuvent être effectués par *Aster* (pas d'élément quadratique de coque).


*   Jusqu'au 9ème mode, l'erreur sur la fréquence est :math:`\text{≤ 2.5\%}` .


*   L'effet de distorsion du maillage n'apparaît vraiment que sur les modes 7 et 12.
