where itot (SI unit: A/m
2) is the sum of all electrode currents in the coupled Electrochemistry interface.
The electrode thickness, s, can typically be coupled to an External Depositing Electrode (External Corroding Electrode) node in the Electrodeposition, Moving Mesh (Corrosion, Moving Mesh) interface, in that case s is calculated as
where s0 is the initial electrode layer thickness, and
Δstot is the electrode thickness change, calculated by the coupled Electrochemistry interface.
