摘要

摘要

En 中文
我们提出了一种简单的数值算法,用于在曲面上生成圆形多孔图案。所提出的数值算法使用显式Saul’yev有限差分法(FDM)在窄带域上求解非局部Cahn–Hilliard方程,并利用求解的数值解在曲面上生成圆形多孔图案。曲面由符号距离函数的零水平集表示,包含曲面的窄带域被定义为距离曲面一定范围内的区域。所提出的算法使用Saul’yev FDM来克服完全显式方案对时间步长的严重限制,保持显式方案的简单性并解决问题。因此,与完全显式方案相比,即使使用相对较大的时间步长,计算解也是稳定的。此外,所提出的算法实现简单。我们在简单和复杂曲面上进行了数值实验。数值实验结果表明,圆形多孔图案在各种曲面上被适当地且高效地生成。
