This bug-report is a duplicate of problem report #44. The problem has been identified as affecting the navigation in replicas (therefore belonging to geometry/volumes subcategory, not tracking) and is currently under investigation. To temporarly overcome the problem, use normal placements instead. Thanks for having provided a testbed program. *** This bug has been marked as a duplicate of 44 *** |
One module of Tile calorimeter in ATLAS has 307 trapezoid periods if I put all 307 periods one by one using Placement - program works and if I put 307 periods using Replica and send any particle along replica axis - particle never exits from the module If I put 300 periods instead of 307 and use replica, I get G4SmartVoxelHeader::BuildReplicaVoxels probable error in replicated geometry, logical volume TileModule_log *** G4Exception: Aborting execution *** The program was tested on atlinux5 with geant4.1.0 and on private RedHat6.1 with geant4.1.1 The program is in /afs/cern.ch/user/t/tilecal/geant4/tileTB in order to produce the output given below one needs to do: cd /afs/cern.ch/user/t/tilecal/geant4 .
