A Simplified Solution Algorithm

The procedure outlined below describes an algorithm for numerical solution of the current distribution. It is typically not the one implemented in practical software since is not efficient. However, for a conceptual description of the procedure it is the simplest to discuss, as it is not hampered by extraneous mathematical considerations. The thin boundary layer approximation is invoked and rather than a complete solution of the flow field, it is assumed that the equivalent stagnant concentration boimdary layer, %, along the electrode is available (may vary with position). The computational routine consists of the following steps applied to numerous points along the electrodes  

Check and update step 1 (60) as necessary. Updating may involve direct replacement of the previous guess with the newly computed values. More advanced updating algorithms, e.g., Newton-Raphson, may be applied for faster convergence.
