Domain, Boundary, Edge, Point, and Pair Nodes for Solid Mechanics
The Solid Mechanics Interface has these domain, boundary, edge, point, and pair nodes and subnodes (listed in alphabetical order), which are available from the Physics ribbon toolbar (Windows users), Physics context menu (Mac or Linux users), or right-click to access the context menu (all users).
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.
Features Available from Submenus
Many features for the Solid Mechanics 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 submenus at the Domain level are Material Models, Volume Forces, Mass, Spring, and Damper, Domain Constraints, and More.
The submenus at the Boundary level are Connections, Mass, Spring, and Damper, More Constraints, Pairs, and More.
There are also the Edges and Points submenus.
Note: Some submenus are only present with certain COMSOL products.
