fortran 求电离层中性风

双馈风机 电磁暂态建模 常用 PSCAD模型(Electromagnetic transient modeling of DFIG)

本代码高效简洁，利用率高。使用时需改动少量参数。主要功能就是利用frotran语言求得时间序列的小波分析结果。(this program is short and effect. only a few parameters need to be modified when used. this main fuction of this program calculate the waavelet of time serises)

Level set solver for two phases flow

一个简单的混沌程序，可以看到分叉的现象和振荡的现象。(A simple chaotic process, you can see the phenomenon of bifurcation and oscillation)

说明：  UMAT子程序例子，mises屈服准则，弹塑性材料，sss(umat subroutine, von mises yield criteria)

说明：  各种cfd的fortran小程序，有sod激波管精确解、近似解，shuosher激波管近似解，包含WENO差分格式，牛顿法；还有网格生成书籍。(Various CFD FORTRAN programs, including SOD shock tube exact solution, approximate solution, shuosher shock tube approximate solution, including WENO difference scheme, Newton method, and grid generation books.)

这是弹性地基梁的有限元计算方法编程的源代码，是书上的，可以用来土木工程的人士学习，希望能有用(This is the finite element method of elastic foundation beam programming source code that can be used to study civil engineering who the book, hoping to be useful)
