Examples
- Overlap grid sweeping
重叠栅形扫雷 - Of course overlap grid also has its shortcoming : in the application of this method , the pre - disposal process of computational grid to find the interpolating connection , so - called “ dig - hole ” process , is hardly to proceed automatically
多年来,重叠网格的应用基本上是根据一套繁琐的处理方法,针对具体外形编写具体程序的处理过程来实现,成为长期以来制约重叠网格应用的瓶颈。 - This method has different consideration with conventional ways , it can reduce the disposal time for almost 100 times , and resolve the efficiency problem successfully . with the help of research in this paper , the capability of using overlap grid has been improved greatly and many old work based on structural - grid , such as difference scheme , turbulence model , can be used in moving - grid field of overlap grid technology and expand our research field for cfd remarkably
通过本文的研究,使我们应用重叠网格处理复杂外形的能力得到显著提升并使我们基于结构网格做的许多研究工作,如各种差分格式以及各种湍流模型的比较研究、大攻角问题等专项研究平滑地过渡到基于重叠网格的动网格应用领域来,较大地拓展了我们的研究应用领域。 - The conventional ways has low efficiency , which result in the application of overlap grid in moving - grid problem , which need re - disposes the interpolating connection in every step in time direction , is very difficult considering the computational efficiency . aim at the above problem in application of overlap grid , this paper using an new manner rooting in analysissitus to put forward a “ method of distinguishing points of intersection ” and develop corresponding computational soft , which could realize the automatic and shape - independent pre - disposal process for overlap grid . to deal with the problem of low efficiency for pre - disposal process in moving - grid , this paper bring forward the “ mosaic ” method and adt method which based on the huge memory of modern computer
对于重叠网格在动网格应用中的计算效率问题,本文通过进一步研究插值信息的高速查询方法,提出不同于传统算法思路,以现代计算机大内存为基础,用计算机物理内存空间换计算时间的” mosaic ”方法以及应用基于二叉树数据结构的adt ( alternatingdigitaltree )方法两类方法,成功的将原处理时间提高了两个数量级? ?即将网格规模在百万量级的重叠网格预处理时间从传统方法的耗时30 60分钟提高到几十秒钟,从而成功解决了这一问题。 - For a long time , user must complete this step with a series of complex methods by hand , and this problem became the choke point in application and development of overlap grid technology . in the moving - grid problem with fluctuant shape , the pre - disposal process of overlap grid is a main difficulty
对于重叠网格对复杂外形适应能力问题,本文借用拓扑学中关于几何外形拓扑关系的新思路,即射线判别法,发展出”重叠网格交点判别法”并编写相应软件,实现了与几何外形无关、无须人工干预的通用、自动化重叠网格预处理。
