[Gate-users] Ion source: empty output

[Débora Salvado]

I increased the verbosity of my simulation to:

/event/verbose 1

and now when I run my simulation, it keeps giving me this message:

=====================================
  G4EventManager::ProcessOneEvent()
=====================================
G4PrimaryTransformer::PrimaryVertex (0(mm),0(mm),0(mm),1.51525e+08(nsec))
1 primaries are passed from G4EventTransformer.
!!!!!!! Now start processing an event !!!!!!!
Track (trackID 1, parentID 0) is processed with stopping code 2
Track (trackID 3, parentID 1) is processed with stopping code 2
Track (trackID 2, parentID 1) is processed with stopping code 2
NULL returned from G4StackManager.
Terminate current event processing.

I've read that some users solved this problem by adding the
RadioactiveDecay process to their physics list. But I have it in my
macro... so can someone help me?

Thanks,
Débora Salvado
