ABAQUS与Python

tarjan算法求解有向图中的简单环，非常好用(Tarjan algorithm is very useful for solving simple rings in directed graphs.)

本程序是完成网络的评价路径长度和聚类系数的计算。(This program is to calculate the average path length and clustering coeffient of a network.)

umat基础知识教学，适合刚接触UMAT的新手做参考(UMAT basic knowledge teaching, suitable for beginners)

说明：  在abaqus中可以实现零厚度的cohesive插入(Implementing cohesive insertion with zero thickness)

说明：  北京航空航天大学航智能控制第二版配套的仿真程序(Simulation program of intelligent control Second Edition from Beijing University of Aeronautics and Astronautics)

直流配网模型，非常基础的直流配网模型，便于对直流配网的基本掌握和学习(DC distribution network model, very basic DC distribution network model, easy to grasp and learn the basic DC distribution network)

说明：  通过EDEM体积力耦合API源程序，实现流体曳力耦合(Through the edem volume force coupling API source code, the fluid drag coupling is realized)

说明：  用Fortran语言编写的abaqus，Dflux热源子程序，路径为环形路径(Abaqus, Dflux heat source subroutine written in Fortran language, with a circular path)

说明：  使用python语言实现复杂网络SIR和SIS模型编程(SIR AND SIS model with python language)

对于非线性模型的跟踪预估问题，摒弃额对非线性函数进行线性化的做法，采用无迹变换处理均值和方差的非线性传递问题。(For the tracking and prediction problem of the nonlinear model, the linearization of the non-linear function is abandoned, and the traceless transformation is used to deal with the non-linear transfer of mean and variance.)
