Network modelling of reaction-diffusion systems and their numerical solution using spice

Abstract Using the circuit analysis package SPICE, we can perform computer simulations of certain nonlinear reaction-diffusion problems in a fraction of the time required by more conventional methods. In this paper we develop the method from first principles and illustrate it with examples of steady-state and transient analysis. An example is provided to show how certain program features facilitate the search for and study of multiple steady states.
