I am familiar with both Ansys and Nastran.  In Nastran, I have used the CBUSH element to connect two coincident independent nodes of two RBE2 elements that spider out to the edges or faces of the holes.

To do the same thing with Ansys, you can create a Joint, type = General and scope the mobile side to one hole and the reference side to the other hole. If you set the Behavior to Rigid, that is like an RBE2 element, if you set the Behavior to Deformable, that is like a Nastran RBE3 element.

You can't define a preload using the above method, but there are other ways to create a preload in Nastran and Ansys.
