Hello everybody! Can anyone kindly explain me how "Rigid Connector" works? Which is the difference between using Rigid Connector or simply creating pairs? Any example? Thank you everybody for the help! Stefano

Hi Stefano,

A rigid connector is a virtual rigid object that can be attached to an arbitrary combination of boundaries, edges, and points. It can be given inertial properties, forces, moments, and spring to ground.

It has no relation whatsoever to a pair. In a pair you have a pointwise local coupling between corresponding points on two boundaries (possibly as a contact condition).

Rigid connectors are used in several models in Application Libraries, for example the tutorial bracket_rigid_connector.

Regards,
Henrik
