摘要
在建立单元向量、伪单元向量等概念的基础上,提出了当不形成总刚度矩阵时,预处理共轭梯度法(PCG)的一种高度并行的EBE计算方法,其基本思想是把PCG法各步的计算都单元化.文[3]中的数值试验结果表明了它的有效性.
Important concepts such as element veCtor, pseudo-element valor are discussed and an EBE cpmputational method of preconditioned conjugate gradient method (PCG) is presented, namely EBE-PCG method, which does not require the formation of global stiffness matrix and is highly parallizable. Numerical example shows it is very efficient.
