I want to simulate the heavy ion from galactic cosmic rays interact with human beings. I have used the physicslist of QBBC FTFP_BERT in main .cc file. Also I have tried physicslist in example "Hadr01" . meanwhile, all patches of Geant4.9.5 and Geant4.9.6 have tried. But, all of them caused fatal error like below. Could you give some hint of what is wrong of my application? **************************************************************************************************** In /gpfs/geng/geant4_9_6_p03/source/processes/hadronic/models/parton_string/management/src/G4VPartonStringModel.cc, line 81: ===> G4VPartonStringModel::Scatter(): fails to generate strings -------- EEEE ------- G4Exception-START -------- EEEE ------- *** G4Exception : had006 issued by : G4HadronicProcess::PostStepDoIt In /gpfs/geng/geant4_9_6_p03/source/processes/hadronic/models/parton_string/management/src/G4VPartonStringModel.cc, line 81: ===> G4VPartonStringModel::Scatter(): fails to generate strings Call for FTFP Target element H Z= 1 A= 1 Unrecoverable error in the method ApplyYourself of alphaInelastic TrackID= 1 ParentID= 0 alpha Ekin(GeV)= 28.6198; direction= (0.522775,0.851613,-0.0382351) Position(mm)= (-1159.84,12.7481,-692.207); material G4_WATER PhysicalVolume <Tracker> ApplyYourself failed *** Fatal Exception *** core dump *** -------- EEEE -------- G4Exception-END --------- EEEE ------- ************************************************************************************
The problem has been fixed in Geant4 version 10.0 (and of course also in 10.1). Please use one of these recent versions of Geant4.
