| As expected, due to different element formulations, we notice a slight discrepancy between the Abaqus S4 element and the SesamX QD4 SHELL element. Besides, the mesh studied for this validation is quite poor but was chosen precisely to amplify any difference that may appear. As mentioned in our blog article about [[https://www.sesamx.io/blog/shell_finite_element/|the shell element formulation]], the SesamX QD4 SHELL element (MITC4) [[https://www.sciencedirect.com/science/article/abs/pii/S0045794917309550|has been proven to behave better than the Abaqus S4 element]]. | As expected, due to different element formulations, we notice a slight discrepancy between the Abaqus S4 element and the SesamX QD4 SHELL-MITC element.
