摘要: The stochastic cellular automaton (CA) model, originally proposed by Dilthey et al.(1997) was further refined and applied to the simulation of dendritic growth controlled by solutal effects in the low Péclet number regime. The use of square cells in the division of the computational domain introduces an artificial anisotropy when growth is simulated by capture of the closest neighboring cells. This artificial anisotropy becomes significant when the preferential growth direction is not aligned with the axis of the cell. The proposed model …
