We derive a foundational equation in the virtual boundary method , and essential conditions that the virtual boundary must satisfy 摘要以位勢(shì)問題為分析對(duì)象,從格林公式出發(fā)嚴(yán)格導(dǎo)出了虛邊界元法的基本積分方程。
Furthermore , according to the feature of widely distributed intertidal regime along the coast , moving boundary method is used to truly simulate the water area with such changes 又根據(jù)沿岸潮灘廣泛分布的特點(diǎn),引入動(dòng)邊界技術(shù)來真實(shí)模擬這類變化的水域。
Second , a visual software for srm electromagnetic field computation is developed by using object oriented programming , in which rotor movement problem is dealt with moving boundary method 第二,用運(yùn)動(dòng)邊界法處理相對(duì)運(yùn)動(dòng),應(yīng)用面向?qū)ο蟮某绦蛟O(shè)計(jì)方法,開發(fā)了可視化開關(guān)磁阻電機(jī)電磁場(chǎng)分析軟件。
Compared pec pmc method with periodic boundary method . basing on these , writes stimulation program for the wave absorber of bowtie patch array loading resistance , and computes its reflectance 比較了電壁磁壁和周期邊界條件兩種截?cái)喾椒?在此基礎(chǔ)上針對(duì)蝴蝶結(jié)型加載阻抗吸波材料,采用c語言編寫仿真程序,計(jì)算了它的反射率。
In this thesis , the tides and tidal currents in the seas adjacent to zhejiang province are simulated with a three - dimensional baroclinic primitive equation model - hamburg shelf ocean model ( hamsom ) . two numerical techniques - nested grid and moving boundary method are used successfully and high precision results which compared with the observed ones are obtained . these results reveal the characteristics and the moving rules of the tides and tidal currents in this area 本文采用三維陸架海模式( hamsom )對(duì)整個(gè)浙江近海的潮汐和潮流進(jìn)行了三維數(shù)值模擬,成功地應(yīng)用網(wǎng)格嵌套和動(dòng)邊界技術(shù)獲得了和實(shí)測(cè)資料相吻合的較高精度的結(jié)果,揭示了浙江近海潮汐、潮流的主要特征和運(yùn)動(dòng)規(guī)律。
A case study is presented for the reachable workspace of the human finger ( flexion / extension planar motion ) , based on the research on the anthropometric data of human finger kinematic parameters and the joint motion range limits , and then 3 - d modeling of fingers reachable workspace using a recursive swept boundary method is constructed 通過測(cè)量活體手指的長度及活動(dòng)度,研究了人體手指幾何和運(yùn)動(dòng)參數(shù)的分布,并用曲面包絡(luò)的方法求出手指可達(dá)工作空間的三維模型。
