The Corroding Electrode node implements
Equation 3-3 (with no source term),
Equation 3-4, and
Equation 3-5. Use this node to define the seed layer thickness, the electrode thickness change, the electrical conductivity, and the electrode current density.
The Seed layer thickness s0 (SI unit: m) defaults to 1x10
-14 m.
Enter a value or expression for the Electrode thickness change Δs (SI unit: m). The default is 0 m.
The default Electrical conductivity σ (SI unit: S/m) uses the value
From material. For
User defined select
Isotropic,
Diagonal,
Symmetric, or
Anisotropic depending on the properties of the pore electrolyte. Then enter any expression for the conductivity as a function of temperature. Then enter a value or expression in the field or matrix.
