Domain, Boundary, Pair, and Global Nodes for the Mathematical Particle Tracing Interface
The Mathematical Particle Tracing Interface has these domain, boundary, pair, and global 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.
