基于元胞自动化模型的三维雪花晶体近似模式的产生(英文)

3D similar pattern generation of snow crystals with cellular automata

关于雪花生长过程的计算机模拟已经受到了广泛关注.其中,元胞自动化模型是一种基于网格和简单规则的计算方法.尽管这是一种简单的模型,但其在模拟复杂过程(比如:生命现象,晶体生长和湍流)时往往能取得较好的结果.提出了一种由传统的二维模型扩展而来的三维雪花晶体生长方法.计算机模拟结果显示提出的方法能够更精确地模拟出三维雪花的晶体化过程.

Computer simulation of snow crystal growing process has been done for many years. Cellular automaton is a computing model which is made from lattice cells and simple rules. Though it is a very simple model,it gives good results when used to imitate complex processes such as the life phenomenon,crystal growth and the turbulent flow. In this paper,a cellular model for 3-Dimensional snow crystallization was proposed by extending the traditional 2-Dimensional cellular model. Simulation results indicated that th...
