I have built a application based on the example of hadr01 in the Geant4 release. My version is 9.2.p01. what i have done is simulate the transportation of neutron with energy of 0.2 MeV to 0.4 MeV.
My problem is: at the end of a run, it print some warning information shown as follows:
Run Summary Number of events processed : 1000 User=2.3s Real=34.15s Sys=0.44s RunAction: End of run actions are started HistoManager: End of run actions are started ======================================================== Beam particle neutron Beam Energy(MeV) 0.3337538732147403 Number of events 1000 Average energy deposit (MeV) 0.1142 RMS(MeV) 0.1094 Average number of steps 16.55 Average number of gamma 3.167 Average number of e- 3.817 Average number of e+ 0.223 Average number of neutrons 0 Average number of protons 0 Average number of antiprotons 0 Average number of pi+ & pi- 0 Average number of pi0 0 Average number of kaons 0 Average number of muons 0 Average number of deuterons+tritons 0.339 Average number of He3+alpha 0.016 Average number of ions 0.004 Average number of forward neutrons 0 Average number of reflected neutrons 0 Average number of leaked neutrons 0 Average number of proton leak 0 Average number of pion leak 0 ======================================================== Closing the tree...

in this simulation, the hadronic process I choose is: QGSP QGSP_EMV QGSP_NQE. what i want to know is: what is the reason of the warning? what is the meaning of the warning? How to resolve this problem?
In addition, when i change the hadron process and choose QGSC_EFLOW only, there is no such kind of warning.
thanks a lot!
