Use a Predefined Multiphysics () node to categorize the multiphysics interfaces in different physics areas. It collects the multiphysics interfaces into more intuitive and quick access groups. Right-click Predefined Multiphysics to add Contained Multiphysics Coupling, Contained Multiphysics Definition, and Contained Interface (Predefined Multiphysics) subnodes.

To add a Predefined Multiphysics node, under Definitions Library right-click Physics Areas and choose it from the context menu.

See Physics Area for the settings.
