I'm using GRAS 3.3 as external application with GEANT4.9.6.p04. I'm building a satellite for LEO mission and taking the macro files from SPENVIS as input. I use QBBC as my physics list.
The simulation runs well for trapped electrons, trapped protons and solar protons. When running with GCR Z = 1 source, I start to get some warning messages:
-------- WWWW ------- G4Exception-START -------- WWWW ------- *** G4Exception : had012 issued by : G4HadronicProcess:CheckResult() Warning: Bad energy non-conservation detected, will re-sample the interaction Process / Model: ionInelastic / Binary Light Ion Cascade Primary: Li7[0.0] (1000030070), E= 15557.6, target nucleus (13,27) E(initial - final) = 6668.06 MeV.
*** This is just a warning message. *** -------- WWWW -------- G4Exception-END --------- WWWW -------
But the simulation ends with no further problems. When I run with GCR Z >= 2, the warning messages become very frequent, till the simulation crashes:

I tried to change the physics list to FTFP_BERT_HP and Shielding, but the simulation still crashes.
I thank very much for help, since I cannot find a solution for the problem.
