Electrode Reaction and
Double Layer Capacitance subnodes are available from the context menu (right-click the parent node) or from the
Physics toolbar,
Attributes menu.
The Electrolyte potential will set the potential value directly, whereas
Total current or
Average current density both add an extra global degree of freedom for the potential in the electrolyte phase, set to comply with the chosen condition.
When using the Total current option in 1D or 2D, the boundary area is based either on the
Cross-sectional area (1D) or the
Out-of-Plane thickness (2D) properties, set on the physics interface top node.
