COMSOL 6.2 - Physics Toolbar

Once physics interfaces are added to the model, the ribbon toolbar (Windows) and the contextual toolbar (macOS and Linux) are replaced with a custom physics or mathematics interfaces toolbars for the selected interface, which contains many of the common features and actions required to add physics and mathematics features for that interface to the Model Builder.
