WebJan 22, 2024 · My guess as to how this works is the three nodes on the solid form a triangular plane that has a unique normal. As those three nodes deform the normal to that plane will move (rotate). That rotation is used, with the beam orientation triad, to determine the rotation at the end of the beam, thus forming the rotational constraint. I am confused ...
