BRUTE FORCE DIGITAL-SIMULATION

The discretised forms of the partial differential electrochemical diff usion-reaction equations can be solved at each time step by simply lea ving them as systems of linear equations, and solving by EU decomposit ion. Under favourable conditions, this can have efficiency comparable with more sophisticated methods of solution and in any case does not o ften lead to unacceptable execution times on modem computers. This is demonstrated by the examples of a simple first-order catalytic mechani sm, a more complex second-order mechanism, and the two-dimensional sim ulation of a potential step at a microdisk electrode.
