model.modelNode()
Deprecated alias for model.component() for accessing model component nodes.
This syntax is still used when you turn off the component syntax (clear the Generate code using component syntax checkbox on the Application Builder>Methods page in the Preferences window). Otherwise, the code that COMSOL Multiphysics creates uses model.component().create(<tag>) instead of model.modelNode().create(<tag>), and so on. See model.component().
