Dear Fluka experts,


I am trying to reproduce GCR spectra in interplanetary space and compare it with the Particle Data Group plot (fig.24.1) :

http://pdg.lbl.gov/2009/reviews/rpp2009-rev-cosmic-rays.pdf


I am using All-particle option (GCR-IONF)


the issue is that the run ends up with the "finished with errors" message and the .out file, Run Summary/Errors doesn't specify what the problem is:


m^2/sr/s ***

 *** Z: 23: Flux: 4.30439E-06 (cum. 0.32600 ) p/cm^2/sr/s Nucl. flux: 2.19513E-04 (cum. 0.43527 ) nuc/cm^2/sr/s ***

 *** Z: 24: Flux: 9.13202E-06 (cum. 0.32601 ) p/cm^2/sr/s Nucl. flux: 4.75371E-04 (cum. 0.43574 ) nuc/cm^2/sr/s ***

 *** Z: 25: Flux: 5.30059E-06 (cum. 0.32602 ) p/cm^2/sr/s Nucl. flux: 2.91532E-04 (cum. 0.43603 ) nuc/cm^2/sr/s ***

 *** Z: 26: Flux: 6.96286E-05 (cum. 0.32609 ) p/cm^2/sr/s Nucl. flux: 3.89293E-03 (cum. 0.43993 ) nuc/cm^2/sr/s ***

 *** Z: 27: Flux: 3.21613E-07 (cum. 0.32609 ) p/cm^2/sr/s Nucl. flux: 1.89752E-05 (cum. 0.43995 ) nuc/cm^2/sr/s ***

 *** Z: 28: Flux: 2.81746E-06 (cum. 0.32609 ) p/cm^2/sr/s Nucl. flux: 1.65552E-04 (cum. 0.44011 ) nuc/cm^2/sr/s ***

  *** NASA - O'Neill (Pinsky) flux ***

  *** Samp. transition energy: 500.

  *** Samp. spectral index: 1.75

  *** Real spectral index: 2.75

  *** Minimum energy: 0.300000012 GeV ***

  *** Maximum energy: 30000. GeV ***


please take a look at my input and let me know what I am doing wrong


thank you


Roman
