Dear Cristian,

I suspect you'll need to make a bug-report (or wait until 9.4 is out and see if the problem persists). From your stack trace, it seems that G4NeutronHPElasticData::BuildPhysicsTable()->G4NeutronHPData::DoPhysicsVector() is not set up correctly in cases where it is called twice. What happens if you just issue /run/beamOn twice? I guess, it'll work. Now, what I don't understand is that when you do NOT set PhysicsHasBeenModified, why the BuildPhysicsTables is still being called from G4RunManagerKernel. In any case, the PhysicsTables should rebuild without a crash because they need to be if a material changes or is added in UpdateGeometry.

I am not the expert here and unfortunately so close before the holidays I have no time to properly investigate. Apart from the question why BuildPhysicsTables is called in your case, the G4NeutronHP is a hadronic problem and you might get more help in that forum.

Best regards, Peter
