此文介绍了由江广山（音译）、舒其望（Jiang Guangshan & Shu Chi-Wang, JCP 126 pp202-228, 1996）等人发展的5阶有限差分WENO格式，并提供用C++语言编写的程序源码（不包括坐标变换模块和化学反应模块的源码），采用了面向对象（OO）思想编写程序。所提供的程序仅适用于简单二维矩形边界、可压缩流动、非定常、Euler方程的数值模拟。经坐标变换，可适用更多其他几何外形的计算。源码在Windows 2000, XP, 2003平台、Visual C++ 2003编译环境下能够良好工作；经过简单地修改也可以在Linux, UNIX下编译通过。(This paper introduces the 5-order finite-difference WENO format developed by Jiang Guangshan & Shu Chi Wang, JCP 126 pp202-228, 1996, etc., and provides the source code (excluding the source code of coordinate transformation module and chemical reaction module) written in C + + language, and uses the object-oriented (OO) idea to write the program. The program is only suitable for the numerical simulation of simple two-dimensional rectangular boundary, compressible flow, unsteady and Euler equations. After coordinate transformation, it can be applied to more calculations of other geometric shapes.)
