I have a doughnut which I am pulling on diagonally from both sides with force / reaction force.
I have successfully added automatic coupling on the splitplane, however when I run the simulation the doughnut rotates. If I add constraints to the circula symmetry surface I will impact the results in a bad way.
I have also tried to add a rotational constraint to the axis/centre splitline, but that did not work since of course solid elements do not have rotational freedom.
Do you have any suggestion? Adding an inertia relief perhaps?
