Feature Nodes for the Lumped Thermal System Interface
The Lumped Thermal System interface has only global nodes. They are available from the Physics ribbon toolbar (Windows users), Physics context menu (Mac or Linux users), or by right-clicking then main physics interface node to access the context menu (all users).
Nodes in the lumped thermal system should not be confused with nodes in the Model Builder tree of the COMSOL Multiphysics software. The system node names are not restricted to numerical values but can contain alphanumeric characters.
In the COMSOL Multiphysics Reference Manual see Table 2-4 for links to common sections and Table 2-5 to common feature nodes. You can also search for information: press F1 to open the Help window or Ctrl+F1 to open the Documentation window.
