COSIMA Activation - Skips Events and Freezes

[joshhooker]

On the 11.2 branch, the simulation will run until the event number is skipped and the events stop updating. All of the files do not continue to be updated.

Running COSIMA with 1 thread and the following options:

#Physics parameters:
PhysicsListHD qgsp-bic-hp
PhysicsListEM LivermorePol
DecayMode ActivationBuildup

#Storage parameters
StoreCalibrated true
StoreSimulationInfo all
DiscretizeHits true

#Particle range cuts:
DefaultRangeCut 0.005

#Simulate the primary protons and all secondaries:
Run Step1
Step1.FileName output.Phase1.BuildUp
Step1.Events 200000000
Step1.IsotopeProductionFile output.Phase1.BuildUp.dat

Any ideas on what would cause this?

Thanks for reporting.

Which branch are you using?
All branches using Geant4 11.2 are early development branches, which just have been tested with COSI. And I know there are still a few bugs left to fix.

Do you want to switch to the main branch which uses Geant4 10.2?

Thank you for the fast reply, Andreas!

I am currently on the feature/geant_11.2 branch.

I am unable to use MEGAlib with Geant4 10.2 because I am using materials with a Z > 92 and Geant4 10.2 appears to have issues with these heavy materials even with the AllowForHeavyElements flag turned on.

Is there a chance you could either email me or upload a geometry file which reproduces this issue?
