Here is a 1D Euler code (1D shock tube code) for solving Sod s shock tube
problem, using Roe s Approximate Riemann solver, minmod limiter, and 2-
stage Runge-Kutta time-stepping. Learn how a second-order non-oscillatory
Euler code is written, or just run it to see how it is capable of computing
discontinuous solutions. Incorporate various flux subroutines given below to
explore other methods.
