Initial Values
Use this node to specify the Initial Values of the electrolyte potential and the electric potential for the solver.
For many electrochemical problems that use non-linear electrode kinetics, such as Butler-Volmer kinetics, providing reasonable initial values can significantly improve solver convergence.
A good value for the Electric potential (SI unit: V) in electrode and porous electrode domains can usually be derived from the boundary conditions. For instance, if a boundary has been grounded or set to a cell potential, use that value as the initial value also in the adjacent domain. For the Electrolyte potential (SI unit: V) a good initial value is often the negative of the equilibrium potential of the grounded electrode.
