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.

There are two multiphysics interfaces which are specific to the Multibody Dynamics Module:
•
The Fluid-Multibody Interaction Interface
•
The Fluid-Multibody Interaction, Assembly Interface
The other couplings are analogous to those available for the Solid Mechanics interface. See also:
