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 HamiltonJacobi equations by applying adaptive moving grid methods of levelsetbased deformation methods. Two numerical examples are given, which show the accuracy and efficiency of computing 'extreme' and 'spikes' of solutions to the HamiltonJacobi equation.
