The GALPROP program ( computes cosmic-ray propagation numerically. To obtain manifestly accurate solutions an explicit method is now available to replace the Crank-Nicolson operator-splitting method. This can be implemented in the public version of GALPROP with the update provided here.
Instructions: replace the four files, propel_diagnostics, and Galdef.h and rebuild the executable.
Add solution_method and solution_convergence to the galdef parameter file. A test GALDEF file with these parameters is galdef_54_reltest09; the diagnostics document the accuracy of the solution.
A full explanation is given in the GALPROP Explanatory Supplement
Thanks to Deepak Khurana for requesting and testing this update.
Now replaced by this project:

  • 2 October 2013: is replaced by a corrected version compatible with the public version. gives more diagnostics and implements the convergence criterion. A test galdef is included.
  • 2 October 2013: a complete release with the new routines is now available as galprop_54_r2160.gz
