I'm working on the mechanical simulation of a rotational system about Z. To reduce the model size, we only consider one unit of the repeating pattern and we'd like to apply periodic boundary conditions.
My model is built with Gmsh and I have already enforced two sets of nodes to be each side of my "unit piece", especially I've forced the mesher to have the same number of nodes for those interfaces and those are exactly matching if rotated (so we have a direct one-to-one relationship).
I'm currently a Quanscient user and they have such a cool feature where you give the center of rotation, axis of rotation, angle of rotation, set #1, set #2 and it will figure out the constraints to make it happen.
Is there such a feature available with Ansys mechanical or do I have to build commands to inforce u'_r = u_r, u'_theta = u_theta, u'_z = u_z in cylindrical coordinates (it will take a bit of head scratching to translate the cartesian coordinates into those)?

Aniket, could you please share here some information that would put me on track?
It seems that as a trial user I can't access the Ansys help portal, which is quite not ideal if I want to trial our main loadcases and decide if we go with Ansys or not...
