ANSYS二次开发自定义破坏准则子程序(ANSYS subroutine)

branchbound就是所谓的分支定界算法，应用于动态规划解决实际问题(branchbound is called the branch and bound algorithm applied to the dynamic programming to solve practical problems)

对病态系统采用了四阶龙格库塔法和蛙跳法进行了仿真，得到了很好的实验结果(Pathological systems using fourth-order Runge-Kutta method and the leapfrog method for the simulation, the experimental results)

代码为偏最小二乘法计算过程的代码，主要部分都有中文解释(Code for the calculation process of partial least squares method)

已知日期，计算出星期几的程序.以过测试。计算正确。请放心使用。(Caculate Weekday)

可以进行简单的数学运算：加、减、乘、除,sin(),cos(),tan()等，还可以对数字进行取余和开方的运算。但仅限于十进制下，还可以进行数的正、负之间的相互转换，exit表示退出, clear表示初始化，有一个 TextField用于显示传来的计算结果；Server端用于监听连接请求、计算发送过来的两数的和、送回数据结果。(Can perform simple arithmetic: add, subtract, multiply, divide, sin (), cos (), tan (), etc. can also figure to take over and prescribing arithmetic. But only under the metric system can also be used for a number of positive and negative between the conversion, exit, said exit, clear that the initialization, there is a TextField to display the results from the calculation Server client connection requests for eavesdropping, calculated sent the two and the number of returned data.)
