VUMAT example

说明：  非常好的地形改正程序，只需要有点位的经纬度，重力值和高程，内附例子和说明。(Program to compute terrain effects on gravimetric quantities.various modes of terrain effects may be computed)

使用奇异值分解来帮助求解最小二乘问题，特别是在方程系数矩阵不满秩的情况下。(SGELSD computes the minimum-norm solution to a real linear least * squares problem: * minimize 2-norm(| b- A*x |) * using the singular value decomposition (SVD) of A. A is an M-by-N * matrix which may be rank-deficient.)

simple算法，Fortran编写，适合流动换热问题(simple algorithm by Fortran)

采用Fortran语言的编写的又一固体潮预测程序，是国际地潮中心推荐的软件(It can be used for tide predicton )

读写sgy格式的文件，采用最先进的流文件读写，还有校新的fortran语句读写，sgy格式。可以很好的做为教材和以及学习。附有ppt讲解所用方法的描述，附有电子文档可以很好的了解sgy格式。

基于PSCAD/EMTDC搭建的一端口高压直流输电系统(one port voltage source converter high voltage direct current system based on PSCAD/EMTDC)

多相流程序。能解决各种多相流问题，基于格子Boltzmann，用Fortran开发的。(Multiphase flow processes. Can solve a variety of multi-phase flow problem, Lattice Boltzmann, with Fortran development.)

说明：  矩阵求逆，使用fortran语言编写，希望能对有需要的朋友有所帮助(Matrix inversion, written in FORTRAN language, hoping to help friends in need)

由PSCAD搭建的双馈点击的控制模型，连接相对简单，容易理解(Click on the control of the doubly-fed model built by PSCAD connection is relatively simple and easy to understand)

介绍了很多atp中的模型原件，比较实用，在网上很难找到(A lot of original models in ATP are introduced, which are more practical and hard to find on the Internet.)
