An exponentially expanding mesh ideally suited to the fast and efficient simulation of diffusion processes at microdisc electrodes. 2. Application to chronoamperometry

In the first accompanying paper we derived an exponentially expanding mesh for use in the simulation of diffusion processes at microdisc electrodes. In this paper we use this strategy in obtaining a solution for chronoamperometry at a microdisc. We show that it is possible to obtain accuracy to better than 0.25% from a single simulation using the same mesh at all times of interest. Demands on computing resources are light, with a full simulation from switch on through to near steady state taking just a few minutes of CPU time. (C) 1998 Elsevier Science S.A. All rights reserved.
