The Woodward-Colella interacting blast wave problem consists of the one-dimensional Euler equations of compressible gas dynamics together with initial data containing two discontinuities in pressure that lead to strong shock waves that interact with one another.

This code is based on the discussion in Example 15.1 of Finite Volume Methods for Hyperbolic Problems by R. J. LeVeque. Figures 15.5 and 15.6 show the solution at time t = 0.038 as computed with various methods.

After running this code and creating plots via "make .plots", you should be able to view the plots in _plots/_PlotIndex.html.
