Flexible object simulation systems are mainly based on geometrical , physical and hybrid techniques . since adopting physical technique can not only embody the appearance but also analyze the internal structure of flexible object and obtain satisfying results , so the algorithm proposed here depends on this technique . the bottle - neck in most flexible object simulation systems is that time steps must be small to avoid numerical instability and the huge computation cost
柔体的仿真方法主要以几何技术、物理技术和混合技术为基础，由于物理技术不仅能反映柔体的外部特征，而且能对其内部结构进行深入的分析，所以在本文进一步研究的过程中，以该技术为主要的研究手段。
Based on tree data structure , the cartesian grids about 2 - d and 3 - d configurations are generated using the surface - cutting procedure . in the course of grid generation , a two - step ray - casting algorithm to excluded cells inside the body and a cell - merging technique to avoid numerical instability are fully developed . after creating these surrounding grids , the cell - cutting algorithm is designed to perform geometry - based refinement of grids , and greatly improve the applicability and quality of grid generation
采用物面切割，基于叉树数据结构，发展了一种普遍适用于二维和三维外形的直角切割网格生成方法；构造两步射线求交算法，删除外形内的固体网格，以及小网格合并算法，确保网格质量和流场计算的稳定性；运用对任意网格的切割细分算法，实现了针对几何外形的自适应网格加密，使得网格生成更具普适性和灵活性。
