Chem6 with gamma error

Physics Processes, Models and Cross Sections

I’m trying to run chem6 example with gamma with 1.25 MeV energy using modified beam_HCP.in. Some threads seems OK, some other threads show “No molecule recorded, energy deposited= 13.61 eV”, and some threads are failing with the following fatal exception:

-------- EEEE ------- G4Exception-START -------- EEEE -------
*** G4Exception : TIME_DONT_MATCH
issued by : G4MoleculeCounter::RemoveAMoleculeAtTime
Time of species e_aq^-1 is 1 ps while global time is 1 us

*** Fatal Exception *** core dump ***

which fails the whole program and I don’t see the output. How can it be fixed?

hi dear @mrxak , did you solve “G4Exception : TIME_DONT_MATCH …” error ? I have the same error too

Dear,
This is because these events (track structures) didn’t create or create enough chemical species for chemical reactions. e_aq stays at 1 ps until the end of simulation (1us). This issue will be fixed for next release.

thanks dear @ngoc , Do you think a change in the amount of energy, distance, or time can be resolved? Someone told me that maybe they solved it. but didn’t solve.
