Domain, Boundary, Edge, Point, and Pair Nodes for the Convected Wave Equation Interface
The Convected Wave Equation, Time Explicit Interface has these domain, boundary, edge, point, and pair nodes, listed in alphabetical order, 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). Continuity in pressure and velocity is the default condition on interior boundaries.
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.
