The one-dimensional Riemann problem, namely the shock tube problem is a typical one-dimensional compressible inviscid gas dynamics, and analytical solutions. It solved numerically using second-order accuracy MacCormack two-step difference scheme. Convenient for beginner and exercises given here to the calculation procedure of the one-dimensional Riemann problem with the calculation of language and writing, for all to learn.
