Dear Geant4 users, I am a new Geant4 user, and I have to simulate a 4pi BaF2 calorimeter. This calorimeter is basically made by paving a sphere thanks to regular pentagons and irregular hexagons. I used geant4 7.0p1 for performing my test My geometry is made of : - 1 cylindical beam pipe in aluminium - 2 hemisphericals neutrons absorbers (NA) (6Li based) - 40 BaF2 crystals (12 regulars pentagons and 28 irregulars hexagons) - 40 Photomulipliers (PMT) with their housing - A spherical honey comb (HC) structure build in a similar way than the crystals Visually everything seems to be all right. But when I want to start a run or when performing an overlapping test the program simply crash. For trying to find the problem I have tested many combination between the various calorimeter components, like for instance: 1) each parts alone = no problem 2) crystals + PMT + HC = aborted 3) crystals + PMT = no problem 4) PMT + HC = no problem 5) crystals + HC = aborted 6) crystals + NA + PMT = aborted 7) crystals + NA = no problem 8) NA + PMT = no problem and so on. At the end I did not succeed to find any logic for crashing or not. In debugging I found the problem came during the "SmartVoxelisation" operation.

If anyone can help it will be for me very invaluable. Thanks in advance
