Propagation of Chemical Waves in Discrete Excitable Media: Anisotropic and Isotropic Wave Fronts
- 107 Downloads
Cellular automaton theory has been recognized as a useful tool for the study and the simulation of wave processes in excitable media (see ) and presents an alternative to the integration of partial differential equations (pde), as used by Tyson et al. . By incorporating only the most important characteristics of the dynamical system into the automaton rules, one can reproduce the dynamical properties of a large system of coupled nonlinear oscillators within a fraction of the computing time that is needed to integrate numerically corresponding partial differential equations.
