Domain, Boundary, and Pair Nodes for the Beam Rotor Interface
The Beam Rotor Interface has the following edge, point, and pair nodes (and subnodes), listed in alphabetical order, and available from the Physics ribbon toolbar (Windows users), Physics context menu (Mac or Linux users), or by right-clicking the main physics interface node to access the context menu (all users).
Features Available from Submenus
Many features for the Beam Rotor interface are added from submenus in the Physics toolbar groups or context menu (when you right-click the node). The submenu name is the same in both cases.
The submenu at the Edge level (3D) is:
•
 Line Constraints.
The submenus at the Point level are
•
 More Constraints
•
 Pairs

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.
In general, to add a node, go to the Physics toolbar, no matter what operating system you are using. Subnodes are available by clicking the parent node and selecting it from the Attributes menu.
The links to the nodes described in external guides, such as the Structural Mechanics Module User’s Guide, do not work in the PDF, only from the online help in COMSOL Multiphysics.
