本文扩展了阈值动力学方法的边界积分格式，以处理材料界面非光滑且可能发生拓扑变化的情况。然后将该方案应用于二维和三维的润湿动力学研究。数值实验表明，与现有的均匀网格方法相比，该方法具有更高的效率，可以在实际范围内精确模拟化学图形化固体表面的三维润湿动力学。
In this paper, we extend the boundary integral scheme for the threshold dynamics method to treat the case where the material interface is nonsmooth and may undergo topological changes. The scheme is then applied to study the wetting dynamics in both two and three dimensions. Numerical experiments show that the scheme is more efficient as compared with the existing method using uniform grids, making accurate simulation of wetting dynamics on a chemically patterned solid surface in three dimensions within practical reach.
