Domain, Boundary, Edge, Point, and Pair Nodes for the Shell and Plate Interfaces
The Shell and Plate Interfaces have the following domain, boundary, edge, point, and pair nodes 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 Shell or Plate 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 Boundary (Shell interface) or Domain (Plate interface) level are
•
 Material Models
•
 Face and Volume Loads,
•
 Mass, Spring, and Damper
•
 Connections
•
 Face Constraints
The submenus at the Edge (Shell interface) or Boundary (Plate interface) level are
•
 Mass, Spring, and Damper
•
 Connections (Shell interface only)
•
 More Constraints
•
 Pairs
There is also the Points submenu.
