基于ausm格式的欧拉方程求解程序，附带有naca0012的翼型数据，是学习计算流体力学的好例程，费尽心思编写的，注释多多，便于阅读-Ausm format based on the Euler equation procedures, comes with naca0012 the airfoil data, computational fluid dynamics is a good learning routines, the effort to prepare, notes a lot

利用AUSM格式来求解欧拉方程,对NACA0012翼型进行流场求解,生成结构化网格(solve euler equation by the method of AUSM,and grid generation is done with structed grid)
