Current
The Current boundary condition sets the total current or average current density over a boundary. It will set a constant electrolyte potential along the given boundary, which satisfies the current value setting.
This node is typically used to model electrode surfaces or boundaries facing an electrolyte reservoir (containing an electrode).
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.
