Summary of results
======================

The model used for the reference solution is based on a theory of resultant efforts with co-rotational formulation [:ref:`bib3 <bib3>`], while that of *Code_Aster* uses a volume approach with a total Lagrangian formulation [:ref:`R3.07.04 <R3.07.04>`].

For this thin shell, the triangle and the quadrangle give good results.
