I am having a problem with my geant4 simulation where I have no idea how to approach the cause, since it occurs so rarely. The error itself is:
G4WT13 > -------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : PART122 issued by : G4ParticleTable::Insert() The particle C16 has already been registered in the Particle Table *** Fatal Exception *** core dump *** -------- EEEE -------- G4Exception-END --------- EEEE -------
G4WT13 > G4WT13 > *** G4Exception: Aborting execution ***
Now I have no idea how to provoke this error. It appears without any pattern. On average it takes more than 1,000,000,000 events (over multiple runs) on 30 threads for this error to occur. In my last run for example it happened after (at least) 154,009,603 events.
I also have exceptions concerning illegal time, energy and/or momentum, which I don't know whether they are linked or not:
-------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : TRACK003 issued by : G4ParticleChange::CheckIt momentum, energy, and/or time was illegal *** Event Must Be Aborted *** -------- EEEE -------- G4Exception-END --------- EEEE -------
These happen more often, probably once every 100,000,000 events, but without any obvious correlation to the other error.
Does anyone have an idea on how to approach this error?
Of course I can provide whatever part of the code is necessary to look into the issue. But since the simulation itself is running fine most of the time, I suspect Geant4 itself.
Best regards, Sebastian
