Abstract
Changes of the grain shapes caused by the grain boundary migration are modelled by a cellular automaton in a quadricrystal. It is shown that a simple local transition rule is sufficient to describe the grain boundary migration also in the configurations containing triple junctions. A process during which two grains shrink and finally disappear is quantitatively assessed. The method of cellular automata is an efficient tool, in particular, for the simulation of those stages of the grain growth processes that are out of equilibrium.
