An important step in understanding crystal growth patterns involves simulation of the growth processes using mathematical models. In this paper some commonly used models in this area are reviewed and a new simulation model of dendritic crystal growth based on the Moore and von Neumann neighbourhoods in cellular automata models is introduced. Simulation examples are employed to find appropriate parameter configurations to generate dendritic crystal growth patterns. Based on these new modelling results the relationship between tip growth speed and the parameters of the model are investigated.
