摘要
主要讨论了在结构网格上,形成了解Hamilton Jacobi方程的基于水平集方法的自适应运动网格算法,数值例子表明此方法计算Hamilton Jacobi方程解的"极值"和"尖钉"的有效性和精确性。
A numerical scheme is presented for solving the HamiltonJacobi equations by applying adaptive moving grid methods of levelsetbased deformation methods. Two numerical examples are given, which show the accuracy and efficiency of computing 'extreme' and 'spikes' of solutions to the HamiltonJacobi equation.
