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)
