ANSYS弹簧建模有限元分析，分析步骤很详细，供大家学习借鉴(ANSYS finite element analysis of spring modeling, analysis steps in detail, for everyone to learn)

常微分方程数值解法，又是一个数值分析的常用算法(Numerical Solution of ordinary differential equations, numerical analysis is a common algorithm)

说明：  任意给定一个M进制的数X，利用栈实现数值转换。(Given an arbitrary number of M band X, use the stack to achieve numerical conversion.)

基于ABAQUS的三维hashin准则算法(A three-dimensional hashin standard algorithm based on ABAQUS)

模型大小延伸程序；及实现快速傅里叶变换的小程序。该两程序通俗易懂，适合初学者(Model extension、 FFT)
