界面演化的局部水平集算法

水平集算法主要是从界面传播等研究领域中逐渐发展起来的一类算法,是处理封闭运动界面随时间演化过程中几何拓扑变化的有效计算工具.论文基于界面演化过程中的复杂拓扑变化,提出一种界面演化的局部水平集算法,解决了不具全局速度的特殊问题的求解问题,也提高了在处理复杂界面的能力和计算效率.

A Local Level Set Algorithm for Interface Evolution

Level set algorithm is a class of algorithms gradually developed from the research area of interface spreading,which is also an effective calculation tool to deal with geometric topology change in the process of the closed interface with time evolution. Based on the complexity topological change in the process of the interface evolution,a local level set algorithm for interface evolution was presented in this paper. The special problems without overall speed could be properly solved,and the ability to handle complex interface and the calculation efficiency was also improved.
