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
柔體的仿真方法主要以幾何技術、物理技術和混合技術為基礎，由于物理技術不僅能反映柔體的外部特征，而且能對其內部結構進行深入的分析，所以在本文進一步研究的過程中，以該技術為主要的研究手段。
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，基于叉樹數(shù)據(jù)結構，發(fā)展了一種普遍適用于二維和三維外形的直角切割網(wǎng)格生成方法；構造兩步射線求交算法，刪除外形內的固體網(wǎng)格，以及小網(wǎng)格合并算法，確保網(wǎng)格質量和流場計算的穩(wěn)定性；運用對任意網(wǎng)格的切割細分算法，實現(xiàn)了針對幾何外形的自適應網(wǎng)格加密，使得網(wǎng)格生成更具普適性和靈活性。
