In the Multiphysics Couplings branch () you can add several Coupling Feature nodes. The coupling features in this list are available to all Multiphysics Coupling nodes. If the multiphysics coupling is in the same builder file, use Local in the Link from list. The coupling features in the Multiphysics Couplings branch of another builder file are also available if you include it as an Import node under the External Resources branch.

You can add several Multiphysics Coupling features under a Physics Interface that links to the same multiphysics coupling but uses different coupling types. The Overriding Rule Settings have to be the same for all these coupling features. This makes it possible to couple several instances of a physics interface when running COMSOL Multiphysics.
