When connecting two parts together, you may find your options limited to use of a contact pair or modeling the fastener itself. However, solid success has been obtained by using the Point Mass feature in Workbench when joining two regions that were not otherwise connected. The Point Mass feature uses the 17x series MPC technology to join a mass21 element to the face of various surfaces. These surfaces can be on multiple parts. With the beta features turned on in the Options menu, the joint can be made either flexible or rigid (rbe3 or cerig style, respectively). Locate the point mass at the center of mass of the joint.

Cochlear implants are electronic hearing devices designed to restore partial hearing. Improvements in cochlear implant design have been demonstrated using shape memory alloys (SMA). SMAs have complex and distinct thermo-mechanical properties. Implant simulations involving pseudo-plastic deformation and shape memory behavior were carried out using ANSYS Multiphysics tools.
