Abstract
In the preceding chapters, a grid with equal intervals in both time and space was assumed (Fig. 1.1, page 3). There are several reasons for deviating from equal space intervals. Firstly, one wants both to minimise the number of points over the concentration profile and, at the same time, to have close spacing near the electrode. Secondly, in some simulations - but not always - there arise sharp concentration changes somewhere in the diffusion space, usually adjacent to the electrode. One then wants to have close spacing in such regions in order to be able to simulate concentration changes at all. This points to adaptive techniques; but first the simpler fixed unequal grid techniques will be dealt with.
