Multiphysics Couplings
It is possible to couple the Multibody Dynamics interface to several other physics interfaces through predefined multiphysics couplings. This section describes the available couplings.
When you add a physics interface for which a predefined coupling is available to the component, a Multiphysics Couplings node appears in the model tree. Under the Multiphysics Couplings node, you can add the required couplings.
