Domain, Boundary, and Pair Nodes for the Electroanalysis Interface
The Electroanalysis Interface has these domain, boundary, and pair nodes available, 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).
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.
A boundary pair occurs when the solutions on two separate surfaces within a simulation are related (such as when two components in an assembly are touching)
These nodes are described in this section:
•

2This is available when the Convection check box is selected on the physics interface Settings window.
Some of the above nodes require that you click the Show button () and select Advanced Physics Options to enable the option in the context menu. This requirement is for Flux Discontinuity, Periodic Condition, Thin Diffusion Barrier, Electrode-Electrolyte Interface Coupling, Porous Electrode Coupling, and Reaction Coefficients.
