MYFEM

  有限元求解柏松方程。本文采用FORTRAN语言编制程序。程序中大部分变量采用有名公共区存储方式存储，这样可以减少内存占用量。 IFG：生成有限元网格信息，即元素节点局部编码与总体编码对照表，节点实际坐标，边界节点编码与边界点上的已知值 GKD：生成总刚一维存储对角元的地址，计算总刚一维存储长度 FIXP：设置已知节点函数值 GK(NI,NJ,ADJ,AIJ)：单元刚度矩阵计算 GF(NI,N,M,LE,YI,FE)：单元列阵的计算 AK(I,J,AIJ)：总刚度矩阵元素迭加 QEB：总刚度矩阵和总列阵合成 BDE：边界条件处理 SOLGS：Gauss-Seidel迭代法求解方程组 UDIFF(NI,NFLAG,UDIF,LE,ADJ)：标准元素内形状函数导数计算 DIFF：节点上 ， 加权平均 (In this program, FEM was used to solve the possion equation. It is implemented through FORTRAN)
