二维三节点有限元计算程序 输入单元及节点信息，计算结构位移。最大单元数5000，最大节点数2000，能够处理集中力、体积力、已知位移等荷载。 采用迭代、回代算法计算线性方程组。能够生成节点的位移、应力及应变值，应力包括个应力分量及主应力值和主应力方向

本代码是《计算机常用数值计算算法与程序 C++版》一书的配套数值拟合与逼近代码，这些C++程序已经在Virsual C++ 6.0环境下通过。注意，在VC++ 6.0中设置好路径，特别是include目录(文件夹)的路径，否则在编译时会出现找不到头文件的错误，使编译无法正常进行。-the code is "commonly used computer numerical algorithms and procedures C version," a book supporting numerical approximation fitted with the code, these procedures have been in C C 6.0 Virsual environment through. The attention of the VC 6.0 installed path, in particular include directory (folder) path, otherwise there will be compiled header files could not find the mistakes and the compiler not normal.
