本文对二维移动网格方法中边界网格点移动处理方法进行了探讨,一种做法是把边界上的网格点的移动速度等同于和它相邻的内部点的移动速度,另一种做法是将边界上的网格移动看作一维情形,结合数值算例分析和比较了两种处理方法的效果。
This paper discusses how to move boundary points in two dimensional moving mesh methods, one method is that boundary points are moved with the same speed of the internal points adjacent to those boundary points ,another method is to move the boundary points by solving 1-D moving mesh equations, several numerical examples are given to analyze and compare the effect of the two techniques for moving boundary points.
