The Electrode node defines the current conduction in the tangential plane. Use the node to define the electrode thickness and electrical conductivity.

The Electrode thickness s (SI unit: m) defaults to 10−14 m.

The default Electrical conductivity σ (SI unit: S/m) uses values From material. Or select User defined. For User defined enter values or expressions for an isotropic or anisotropic conductivity. Select Isotropic, Diagonal, Symmetric, or Anisotropic depending on the properties of the electrolyte. To use another type of temperature dependence than a linear temperature relation, enter any expression for the conductivity as a function of temperature. Then enter a value or expression in the field or matrix.
