Simulating the Ising Model on a Cellular Automaton

A computer working as a cellular automaton is used for simulating the 2-D Ising model. CA Ising models have been developed by Vichniac, Pomeau and Herrmann. Their model works fairly well at high temperature but freezes at low temperature. The Creutz model with localized “demons” is also a CA model but can be suspected to freeze at low temperature.
