The physics list used was FTFP_BERT. The URL is updated with the output log of the file - in case additional information could be gleaned. A first inspection does not find more useful information in this file. NOTE: this link/file will have a limited lifetime (length tbc). Have not been able to reproduce this problem. Ran 125 million interactions, at this and nearby energies. No crashes found. Code inspection is ongoing. Vladimir has tagged the fix for G4FermiPhaseSpace and it is under stt testing The protection is added to the code the exception should not happen anymore. The fixed code is available with Geant4 9.5beta. The problem should be closed. VI |
ATLAS reported that every 1 per 1000 run of their latest test production reported the following exception: In src/G4FermiPhaseSpaceDecay.cc, line 77: ===> G4FermiPhaseSpaceDecay::KopylovNBodyDecay: Error sampling fragments momenta!!
