各向异性q模拟， 适应于地震资料处理反演实验(U-58 Ani Q- Anisotropic Q modeling Yaping Zhu May 2006 Confidential to the Consortium until 1 Aug 2009 Contents of this directory are Matlab packages to perform the following tasks. HomoPlaneAttVTI, Yaping Zhu, complex wavenumber for "homogeneous" plane P-SV wave propagation in VTI media with VTI attenuation Note: "Homogeneous" here means that the real and imaginary parts of the wavevector are parallel to each other. HomoPlaneAttORT, Yaping Zhu, complex wavenumber for "homogeneous" plane P-wave propagation in orthorhombic (ORT) media with ORT attenuation Note: "Homogeneous" here means that the real and imaginary parts of the wavevector are parallel to each other. RotCij, Yaping Zhu, Bond transformation of the Cij matrix (6x6) EffQTI, Yaping Zhu, Effective attenuation- and velocity-anisotropy parameters for finely-layered VTI media composed of arbitrary number of constituents )

burgers方程求解，采用fortran编写，有详细的说明，效果非常好(burgers equations, using fortran prepared a detailed description of the effect is very good)

说明：  使用此子程序定义非均匀的分布式机械负载（压力和体力）。 当负载是时间和/或位置的复杂函数时，通常使用用户子程序DLOAD。 通常可以用* AMPLITUDE选项建模简单的时间函数。 子程序也可以用来定义一个随元素号和/或积分点数而变化的负载。(This subroutine is used to define non-uniform distributed mechanical loads (pressure and physical force). When the load is a complex function of time and/or location, the user subroutine DLOAD is usually used. A simple time function can usually be modeled with the * AMPLITUDE option. Subprograms can also be used to define a load that varies with the number of elements and/or points of integration.)

平面单元四边形八结点单元的应力应变分析,考虑了应力应变梯度(the analysis of 2D plane including stress and strain)

some different types of VOF codes

MPI与Fortran的并行程序实例，ＳＵ最新源码，实用 (MPI parallel program with Fortran instance, SU the latest source code, and practical )

读入原坐标系下的点数据“1m new.txt”，经过程序运算后坐标轴在x方向上平移3000，y方向平移6000，数字可根据具体工况修改，坐标旋转了47°，也可修改，最后输出坐标变换后的点数据。
