Dear all, I seem to find a mistake in the implementation of the MITC4 shell element, in the miscellaneous example 12.
In the reference used, "Modelisation des structures par elements finis, Vol. 3: Coques.", on page 372 equation 6.3.90 it only added a small drilling stiffness. This was done by a coefficient alpha that is sufficiently small (1e-4 to 1e-7). However, in line 779 <https://github.com/libMesh/libmesh/blob/master/examples/miscellaneous/miscellaneous_ex12/miscellaneous_ex12.C#L779>of the code (corresponding to this equation), this coefficient is dropped. Could anyone please help discuss this issue?
