Matlab_ISR Model

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.)

说明：  udf算法，FLUENT模拟定义，在不同时间变热流密度下进行用户自定义设置(Temperature UDF algorithm)

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

节点度是指和该节点相关联的边的条数，又称关联度。 特别地，对于有向图， 节点的入度 是指进入该节点的边的条数; 节点的出度是指从该节点出发的边的条数。(Node degree refers to the number of edges associated with the node, also known as the degree of association. In particular, for a directed graph, The ingress of a node is the number of edges entering the node; The out-degree of a node is the number of edges that start from that node.)

说明：  通过对导热方程的推导，利用有限体积法，在matlab进行编程模拟，阐述对流传热的机理。(Based on the derivation of heat conduction equation, the finite volume method is used to simulate in MATLAB, and the mechanism of convective heat transfer is described.)

说明：  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)

计算井筒注入或者生产过程中的摩阻系数，可用于井筒压力分布预测(Wellbore fraction coefficient calcuation method)

说明：  三相桥式全控整流电路仿真，使用晶闸管进行三相桥式全控整流电路仿真。(Three-Phase Full-Bridge Controlled Rectifier)

电弧炉仿真模型，自己建的模型，很好用的，PSCAD仿真(Simulation model of electric arc furnace)

一个基于二阶广义积分器的锁相环仿真模型，可以测得三相正弦信号的相位和频率(Phase-locked loop simulation model based on Nikai Hiroyoshi integrator)
