By using the substitute structure approach , a rational linear iteration method is proposed where a target displacement is specified and the required design force , member strength and stiffness are obtained 其藉由使用替代結(jié)構(gòu),將原本復雜之結(jié)構(gòu)非線性問題轉(zhuǎn)化為簡單易懂且較為設計者接受的線性迭代問題。
This paper develops user - defined model and user program interface based on the envirenment of psasp / upi to realize facts control . the calculation of ttc is solved by repeatitive linear iteration based on sensitivity computation 采用基于靈敏度計算的反復線性迭代法,編寫dll格式的用戶程序與psasp接口,實現(xiàn)了ttc的尋優(yōu)計算。
Three temperature equations include disconnected thermal conductivity coefficient and energy exchange terms between electron and ion , electron and photon , which are affected by the density an d temperature of the plasma , and by the atom parameter . implicit scheme have to be used to solve them . we use entirety linear iteration method to do this work 三溫方程含有間斷的熱傳導系數(shù),存在著電子與光子、電子與離子的能量交換,這些量與離子的密度、溫度和原子物理參數(shù)有關(guān),對它們的求解必須采用隱式格式,我們采用整體線性化迭代格式迭代求解。
