摘要： 本文讨论按等距原则重新划分拉氏网格的技巧,应用重分阈值η和四步重分方法。新、旧网格之间,按体积份额守恒地分配有关网格量,数值试验表明,为了提高重分效果,不仅需要调整重分区域内部网格点的位置,而且还要适当调整边界网格点的位置。
Abstract: In this paper, the rezoning technique for Lagrangian meshes is discussed with equidistant principle. A Rezoning threshold value η and fourstep rezoning methed are applied. According to volume ratio, the concerned parameters of meshes between new and old one are redistributed conservatively. The numerical tests show that in order to improve the effect of rezone, not only the position of inner mesh points but also the position of bourdary points are needed to be readjusted.
