The Global Multiphysics Coupling node () defines a multiphysics coupling that can only exist (have selections) on the global geometric entity level (entire model), which means that the Settings window for the feature instance does not contain a selection list.

To add the Global Multiphysics Coupling node, under Building Blocks, right-click the Multiphysics Couplings branch node to add this from the context menu. You can right-click the Global Multiphysics Coupling node to add many features.

See Generic Multiphysics Coupling for the settings.
