PERBC Selecting Nodes from neighboring components?

Hi everyone,

I am trying to run a cyclic-symmetry (periodic boundary conditions on sector faces) Rotor model with PARAM,LGDISP,1.

As you can also see in the picture from radial displacement plot, some nodes between components seem to be sticking together

The Contacts are with static friction coefficient. And the nodal sets I'm using for the RELOC,PERBC commands are seperated into various components (i.e. different node set for disk, shaft etc.)

I was wondering if there is an easy way to tell OS to try matching nodes from the same component only.

Thanks,

Alper
