We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Both models use the same element formulation, ELFORM 16.  I also checked the strain profiles through the thickness using eloutdet which was identical for both and gave the correct profiles.  Everything I checked has been relatively the same except for the deflection.  Most of what is discussed in the page you sent, I have also tried.  While hourglassing did not look like an issue, a college of mine recommended trying hourglass control anyway. That, LMSHT, and SHRF (we suspected maybe an increase in shear force may lead to more deflection) has not effected the delfection for SHELL_COMPOSITE.

Increasing the number of layers did improve the solution.  Just out of curiosity, is it possible to improve the solution in a different way without increasing the number of integration points?
