CLAWPACK Sample CodeBurgers' equation with a transonic rarefaction wave. Comparison of results obtained with or without the entropy fix. This is set in the Riemann solver rp1.f [.html] by modifying the variable efix and recompiling. Note: also try changing mx in setrun.py [.html] to an odd value (e.g. 61 instead of 60). Then there is one grid cell with the value 0.5 at x=0 and a different weak solution is obtained. Note: The solution also looks much smoother if you set order=2 in rp1.f [.html] instead of order=1.
Example [book/chap12/efix]
to accompany the book Converted to Clawpack 4.4 form in 2009.
Plots of resultsAfter running this code and creating plots via "make .plots", you should be able to view the plots in _plots/_PlotIndex.html .

Data filesWarning: These files are generally changed when setting up a run and the versions here may not be the ones actually used.
Library routinesIn addition to the Fortran routines in this library, several library routines from $CLAW/clawpack/1d/lib are used. See the Makefile [.html] to determine which ones are used.
