ansys二次开发

基于Biegler动态优化正交配置法（联立算法）的matlab 代码，由M.Cizniar，M. Fikar等编写(dynopt is a set of MATLAB functions for determination of optimal control trajectory by given description of the process, the cost to be minimised, subject to equality and inequality constraints, using orthogonal collocation on fi nite elements method.)

本程序是采用有限体积法求解二维对流扩散方程的经典程序。程序里包含各种离散方法，划分网格方法等。适合CFD初学者阅读。(The program is two-dimensional finite volume method for solving convection-diffusion equation of the classic program. Program includes a variety of discrete methods, meshing methods. CFD for beginners)

求解速度压力耦合的Simple半隐式迭代方法，该方法在计算流体动力学中应用极为广泛(To solve the pressure velocity coupling Simple semi-implicit iterative method, the method applied in the Computational Fluid Dynamics an extremely wide range of)

符号积分法，有中文注释，大家试试，供参考学习~(Symbolic integration, notes in Chinese, we try, for reference to learn ~)

数值分析中用C 语言验证验证Gauss列主元消去法。(Numerical analysis using the C language to verify verify the Gauss column principal component elimination.)

说明：  无约束优化中的共轭梯度算法程序，解压缩后就可以用了(Unconstrained optimization of the conjugate gradient algorithm procedure can be extracted after the)

用C++编写的一维和二维快速傅里叶变换程序(Prepared with C++ one-dimensional and two-dimensional fast Fourier transform procedure)

说明：  同伦连续算法，很好得用来求解非线性方程组(Homotopy continuation method, may very well be used to solve nonlinear equations)

说明：  复数函数与积分变换 Fourier变换 Laplace逆变换(Complex number function and integral transformation Fourier transformation Laplace inverse transformation)

最小二乘法拟合进行n次多项式拟合，N用来控制拟合的次数，例如N=5时进行4次多项式拟合，还回的是拟合系数(Least squares fit polynomial n times, N is used to fit the number of control, e.g., N = 5 When quartic polynomial fitting, further back are fitting coefficients)
