Possibility to define Fixed Constraints only for certain degrees of freedom?

Please login with a confirmed email address before reporting spam

As part of the topology optimization of a part attached to rods I am looking for ways to restrict only certain DOFs at the mounting points. For example, I would like to restrict the mouvement of the inside surface of a mounting hole only in z direction and not in the other five degrees of freedom. So far I have only found the fixed constraint otpion; however this restricts motion in ALL directions. Does anyone have a clue on how to achieve this?

The Prescribed Displacement node allows constraints in some or all axes.
