The Initial Values node is a subfeature and it adds an initial value for the electric potential V and charge carrier density that can serve as an initial condition for a transient simulation or as an initial guess for a nonlinear solver.

Enter a value or expression for the initial value of the Electric potential V (SI unit: V). The default value is 0 V. Depending on the Material model setting of its parent feature, enter a value or expression for the initial values of charge carrier densities.
