Thank you again for your help, Makoto.
My plan is to place only the gold marker in the parallel world. There is no overlap of the CT volume with the nozzle geometry. I'll try to add the box around the sphere as you suggest.
The problem I am having seems to be when I try to add a magnetic field to a geometry that contains a parallel world.
As a test, I modified example RE06, adding the following code to the bottom of RE06DetectorConstruction::SetupGeometry().
G4UniformMagField* pMagField = new G4UniformMagField(G4ThreeVector(0, 0, 1.0)); G4FieldManager* pFieldMgr = G4TransportationManager::GetTransportationManager()->GetFieldManager(); pFieldMgr->SetDetectorField(pMagField); pFieldMgr->CreateChordFinder(pMagField);
I didn't change anything in the parallel geometry. It crashes in G4ParallelWorldScoringProcess::AlongStepGetPhysicalInteractionLength around here:
//++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ // ComputeStep //++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ returnedStep = fPathFinder->ComputeStep(fFieldTrack,currentMinimumStep,fNavigatorID, track.GetCurrentStepNumber(),fGhostSafety,eLimited, endTrack,track.GetVolume());
The last thing it outputs before it crashes is:
!!!!!!!! Filter: auxiliary points are being memory leaked !!!!!
If I comment out the call to SetDetectorField it works normally. Is there something about magnetic fields and parallel worlds? Do I have to set the magnetic fields in both worlds?
Thanks again! -Ken
