Boundary, Edge, Point, and Pair Nodes for the Electrode, Shell Interface
The Electrode, Shell Interface has these 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).
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.
These physics nodes are described in this section:
•
Boundary Current Source
•
Corroding Electrode
•
Current Source
•
Electrode
•
Electric Insulation
•
Electric Potential
•
External Current Density
•
Ground
•
Initial Values
•
Normal Current Density
These nodes are available and described for the Current Distribution interfaces, where edges (3D components) or points (2D and 2D axisymmetric components) are selected instead of boundaries.
•
Electrode Potential
•
Electric Reference Potential
For axisymmetric components, COMSOL Multiphysics takes the axial symmetry boundaries (at r = 0) into account and automatically adds an Axial Symmetry node to the component that is valid on the axial symmetry boundaries only.
In the COMSOL Multiphysics Reference Manual see Table 2-3 for links to common sections and Table 2-4 to common feature nodes. You can also search for information: press F1 to open the Help window or Ctrl+F1 to open the Documentation window.
