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

新的屈服准则ABAQUS子程序UMAT，含有多种较新的准侧，能很好运用(The new yield criterion ABAQUS subroutine UMAT contains a variety of newer standards and can be used very well.)

模拟退火算法与支持向量机算法的结合，提高了效率与精度(The combination of simulated annealing algorithm and support vector machine algorithm improves efficiency and accuracy.)

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.)

说明：  matlab画三维凸包，根据一些离散点，效果非常好(Matlab draws three-dimensional convex hull, according to some discrete points, the effect is very good.)

单相z源逆变器matlab仿真模型。(Matlab simulation model of single-phase Z source inverter)

说明：  六边形蜂窝自动建模插件，能在abaqus中自动建立蜂窝模型(Hexagonal honeycomb automatic modeling plug-in)

说明：  根据一设定运动轨迹进行模糊pid观测器设定，让后进行跟踪，实现有效跟踪。(According to a set motion trajectory, the fuzzy PID observer is set, and then the tracking is carried out to achieve effective tracking.)

多目标优化的最大妥协解，转换成单目标优化 三人博弈的部分(The maximum compromise solution of multiobjective optimization)

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