Shared Physics Features in the Current Distribution Interfaces
Domain, Boundary, Pair, Edge, and Point Nodes for the Electrochemistry Interfaces
Electrochemistry Interfaces interfaces have 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).
Most nodes and features described in this section are available for all the Electrochemistry branch interfaces unless otherwise indicated.
In general, to add a node, go to the Physics toolbar, no matter what operating system you are using. Subnodes are available by (right) clicking the parent node and selecting it from the Attributes menu.
