Hi everyone, Recently, I tried parallel geometry in my simulation code under Geant 4.9.1, but I have a problem when I using DefineWorldVolume() function to change the geometry between runs. I found that if I do not change geometry between runs, the simulation with parallel geometry is okay, but if I change geometry using the following code, there comes a segmentation fault. G4GeometryManager::GetInstance()->OpenGeometry(); runManager->DefineWorldVolume(detector->Construct(),true); And if I give up parallel geometry, the simulation is also ok. I wonder if I can use parallel geometry and the above code to change geometry between runs at the same time. And, how can I achieve the objective? Any suggestion is highly appreciate! Yours Sam
