Modified forms of transom conditions are presented and one of them appears to be more effective and stable in the numerical implementation of transom conditions 給出了方尾條件的若干改進(jìn)形式,其中一種在數(shù)值實(shí)現(xiàn)方尾條件時(shí)顯得更加有效和穩(wěn)定。
In order to implement efg method through computer program , the discrete equation from the variational principle ( weak form ) and the numerical implementation are described 再次,論述了無網(wǎng)格伽遼金方法的位移近似函數(shù)和權(quán)函數(shù),給出了變分方程及離散方程,以及數(shù)值求解的實(shí)現(xiàn)。
