用于求解一维气体动力学的欧拉方程代码，采用戈东诺夫格式，显式推进，可仿真非定常激波管(For solving one-dimensional Euler equations of gas dynamics code, using Godunov format, explicit advance, can simulate unsteady shock tube)

利用abaqus软件建模，然后将inp文件导入flac软件中。(ABAQUS software is used to model, and then the InP file is imported into the FLAC software.)

基于Matlab的RCS(雷达散射截面）计算案例。 利用时域有限差分法(FDTD)的计算电磁学手段，给出了较为准确的结果。(An exact example to calculate the RCS based on Matlab. Using the FDTD method, it indicates that the simulation is quite acurate.)
