Boundary, Edge, Point, and Pair Nodes for the Membrane Interface
The Membrane Interface has these 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 Membrane 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 level are Material Models, Face and Volume Loads, Mass, Spring, and Damper, and Face Constraints.
•
The submenus at the Edge (3D) or Points (2D axisymmetric) level are Mass, Spring, and Damper, More Constraints, and Pairs.
•
For 3D components, there is also a Points submenu.
