ABAQUS_UMAT的开发

蠕滑力计算,滚珠轴承中蠕滑力计算时用到，修改后也可以用到滚珠丝杠中(fastsim function F=Get_Fastsim(C,Cp,ab,N))

动态因子copula模型建模并模拟分析系统性风险(Dynamic Factor Copula Model Modeling and Simulating Analysis of Systematic Risks)

说明：  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)

三维比例导引法仿真，可以攻击静止/机动目标(Three dimensional proportional navigation simulation can attack stationary / maneuvering targets)

说明：  用MACCORMACK方法求解一维LAVAL管亚音速流动(solve one dimensional laval tube with the method in maccormack)

逆流套管式换热器仿真小程序，工质物性调用refprop,所以需要自行嵌套refprop(Counter flow sleeve heat exchanger simulation small program, physical properties call RefProp, so need to self nest RefProp)

包括GPS仿真的全套代码，matlab和C#。GPS信号的模拟、捕获、追踪，以及数据的处理，极限的解算，周跳的探测及整周模糊度的接算。有用的资料与大家共享后才能体现其价值，希望同仁们也能及时共享比较好的资料，大家一同探讨、进步。(ncludes a full set of GPS simulation code, matlab and C#. GPS signal simulation, capture, tracking, and data processing, limit solution, cycle slip detection and integer ambiguity. Only when useful information is shared with all of you can it reflect its value. We hope that colleagues can also share better information in time, and everyone will discuss and progress together.)

计量模型，garch，var，用于建立各类模型，评估，roc等等(Econometric models, garch, var, used to build various models, evaluations, roc, etc.)

abaqus经纬编织织物模型，umat子程序(ABAQUS warp and weft knitted fabric model, UMAT subroutine)

说明：  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.)
