我们将阈值方法扩展到各向异性设置的障碍物上平均曲率流的数值实现，其中界面能量取决于界面的方向。这种类型的方案隐式地处理接口，支持拓扑变化的自然实现，例如合并和分裂，并使该方法对材料科学的应用具有吸引力。新方案中的主要工具是先前研究中开发的卷积核，它以非局部方式逼近给定的各向异性。我们提供了有关所提出算法的数值特性的详细报告。
We extend thresholding methods for numerical realization of mean curvature flow on obstacles to the anisotropic setting where interfacial energy depends on the orien- tation of the interface. This type of schemes treats the interface implicitly, which supports natural implementation of topology changes, such as merging and splitting, and makes the approach attractive for applications in material science. The main tool in the new scheme are convolution kernels developed in previous studies that approximate the given anisotropy in a nonlocal way. We provide a detailed report on the numerical properties of the proposed algorithm.
