i am running a simulation for a shock tube to test the accuracy of explicit and implicit upwind schemes. For the explicit schemes the iterations are less and quite accurate in comparison with the exact solution at t = 0.24sec. However, for the implicit method, the information propagates much slower t and takes longer than 0.24 sec to reach the similar state. Hence I am not sure how to 'match it up' it with the exact solution at t = 0.24
