Dear Community,
I recently switched from ANSYS Mechanical to COMSOL Multiphysics. So far I was able to transfer my models to the new platform but I yet miss one feature of ANSYS in COMSOL. I hope someone is able to help me out.
What I am talking about is the ability to "couple" (Ansys term) nodal degrees of freedom. In my case this would mean that the displacement of any node in a set of nodes (a surface for instant) is equal and not predefined. We are using this feature to model one eigth of an pseudo-infinitesimal cube of material. Three surfaces of the cube are subject to classical mirror symmetry and the opposite surfaces stay parallel to allow for volume change. The x-y-surfaces are subject to u_z(x0) = 0 and u_z(x_n) = coupled.
In Ansys, this feature is available as the APDL command "CP". It is not available in the GUI. I need this feature primarily for the solid mechanics solver of COMSOL. If anyone knows the name of this feature in COMSOL or can recommend a workaround please feel free to answer.
Thank you very much,

Hi,
sounds that you are looking for periodicity, which is well defined in Comsol.
Hope it helps
Dear Felix,
Did you manage to find a way to get the coupling feature you were looking for? I am trying to do the same and your help would be much appreciated! What was your approach?
Thanks.
