Dear Geant4 users and developers
I am trying to get energy deposition from a multilayer geometry, but I am getting energy bumps in the interface region. My geometry set up is quite simple: four layers constructed with G4Box inside a world filled with vacuum where I shoot electrons. For testing purpose I used the same material in all layers (in this case water). But I got strange energy bumps around the interfaces!
My simulation is based on the brachytherapy example and novice example N04. But there are some differences: I am using one SensitiveDetector and one ReadOutGeometry for whole target, just because I want one plot with the energy distribution through the layers.
Am I doing something wrong? Or, is this a Geant4 bug?
Before someone ask me I tested two other cases, where the layers are sharing interfaces and with a small gap between them (50nm). In both cases I got the same strange energy depositions around interfaces.
If someone need, I can provide plots and other data.
