在水平集(level-set)方法中,通过光滑标记函数F(x,t)来识别不同的流体区域,该函数在一种流体中为正,在另一种流体中为负。流体之间的边界由F(x,t)=0水平曲线来标识。Level-Set函数随流体移动,因此根据: 零水平集曲线的运动仅依赖于法向速度分量。可以通过以下方式找到法线: 将公式(4.12)中的∇F替换并使用u...

The level set method does not deal with the structure boundary directly and the level set function evolves according to the level set equation[21]: ϕt+V→∙∇ϕ=0, whereϕtis the derivative ofϕto timet.V→is the velocity. Here, time and velocity are two variables controlling ...

水平集方法(LevelSetMethod)由Osher和Sethian [1] 于1988年提出后,引起了人们的广泛的注意。 水平集方法不需要显式地追踪运动界面,避免了对拓扑结构变化的处理,计算稳定,已经应用到诸多领 域,如材料学、流体力学、图象处理、计算机视觉、网格生成等。LevelSet法是90年代国外很盛行的方 ...
