Extensions of the Simulation Method

The partial differential equation for linear diffusion and solution chemical kinetics is  

The solution of this equation in terms of the EFD method was described in Chapter 4. 

A discrete form of the diffusion term on the right-hand side of Equation 

The capacitive current is also calculated as in Reference 1, using the IR drop corrected potential in calculating the capacitive charging current at each time step in the simulation. 

Although diffusion and chemical reaction are concurrent processes in the explicit finite difference method, they are calculated separately. This procedure.
