The core of smoothed particle hydrodynamics (SPH) is the nearest neighbor search subroutine. In this paper, a nearest neighbor
search algorithm which is based on multiple background grids and support variable smooth length is introduced. Through tested
on lid driven cavity flow, it is clear that this method can provide high accuracy. Analysis and experiments have been made
on its parallelism, and the results show that this method has better parallelism and with adding processors its accuracy become
higher, thus it achieves that efficiency grows in pace with accuracy. 相似文献

一天,我正在批改学生的作业,忽然,从一个表现不错的女生本子里掉出一张纸条。纸条的大意是说她遇到了一件烦心的事,一名同班的男生提出要与她做个特殊朋友,她不情愿,但对方很执着,她不知所措,希望老师帮助她。她在纸条“保密”二字的后面用了三个大大的惊叹号。我明白她的苦心, 相似文献

二战时期美国著名将军巴顿的新兵训练营接收了一批新兵，这些新兵文化水平低，又沾染上不少坏习惯。为了使他们成为标准的军人，训练营的军官不是靠强制，而是印发一些家信要新兵们读，学着写信，无非是告诉家人，他们在军队里养成了新的生活习惯，如每天早起刷牙，夜晚睡觉前洗脚，衣服鞋袜放置有序，天冷开窗睡觉 相似文献

成功的导言设计,一开始就能扣住学生的心弦,唤起他们探索的欲望,使学生积极地参与教学活动。下面就自己的教学实践谈一谈导入生物新授课的几点体会。1.社会热点导入法利用与新授课内容有关的社会热点作课堂导入,能引起学生的关注,激发求知欲望,为新知识的学习做好心理准备。如在讲“传染病”时,可从今年春天广东等地发生的“非典型肺炎”谈起导入新课,进而引出“传染病”的概念,引导学生总结传染病的特点;在“环境保护”一节的导入中,可以介绍我国的沙尘暴,20世纪60年代为8次,70年代13次,80年代14次,90年代23次,2000年春季就达7次,波及大半… 相似文献

Efficient communication is important to every parallel algorithm. A parallel communication optimization is introduced into
lattice Boltzmann method (LBM). It relies on a simplified communication strategy which is implemented by least square method.
After testing the improved algorithm on parallel platform, the experimental results show that compared with normal parallel
lattice Boltzmann algorithm, it provides better stability, higher performance while maintaining the same accuracy. 相似文献
