The Initial Values node adds initial values for the concentrations ci and the electric potential V that can serve as an initial condition for a transient simulation or as an initial guess for a nonlinear solver. Add more Initial Values nodes from the Physics toolbar.

Enter values or expressions for the initial value of the Concentration ci (SI unit: mol/m3) (except the one that a mass constraint determines) and for the Electric potential V (SI unit: V). The default concentration values are 0 mol/m3 and the default electric potential is 0 V.
