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 the growth process of snowflakes has received much attention, of which the cellular automation model is a grid-based and simple rule-based calculation method.Although this is a simple model, it is very useful in simulating complex processes such as: Life phenomenon, crystal growth and turbulence), a new method of 3D snow crystal growth derived from the traditional two-dimensional model is proposed.Computer simulation results show that the proposed method can simulate more accurately Three-dimensional snowflake crystallization process.
