weno5求解sod激波管问题，是初学计算流编程时做作业的题目，供参考(sod shock problem solve by weno5 for reference)

一个用于弹性接触分析的边界元fortran源程序(One for the analysis of elastic contact BEM fortran source)

该程序通过编写fortran，得到abaqus之程序usdfld，并实例分析。(The program is by writing fortran, get abaqus procedures usdfld, and case analysis.)

编程珠玑有一条项链，它由 N 个随机排列的红、白和蓝色的珠子组成（3< =N< =350(Abas programming there is a necklace, which consists of N random with red, white and blue components of the beads (3 < = N < = 350)

说明：  abaqus周期性边界条件代码，可以参考学习(ABAQUS periodic boundary condition code can refer to learning)
