Radial dam-break problem for 2D shallow water equations. Subdirectory 1drad contains code to solve 1d radially symmetric equations on a fine grid. First run this code. After running 2d code, with same set of output times as in 1drad, you can compare a scatter plot of the 2d results with the 1d results by setting PlotType=4 in plotclaw2. WARNING: This example was modified February, 2006 to use Version 4.3 of clawpack and the associated matlab scripts.
