Hello everyone,
I want to learn, how to introduce rotational DoFs on a bric element.
So far, I have tried to add one support in the center of the face and couple all nodes of the face to this support (using coupling elements as you can see in the attached file). Then I was able to add the rotations. Nevertheless, I want to compare it, because when extracting the stiffness matrix of the element I am not getting accurate results.
Regards
