Dear Forum users and Geant4 Developers,
When I simulated optical photons (OP) with Geant4, the simulation was interrupted by (maybe) memory problem. The problem is (maybe) due to the G4MaterialPropertiesTable class. In G4MaterialPropertiesTable, data of MPT are lost during our OP simulation.
To test this problem, Geant4 source code (version 10.03.p01) was compiled with debug option, and our OP simulation was performed with GDB. Please see attached two screenshots. First screenshot shows the inside of GetProperty() of G4MaterialPropertiesTable class, As shown in Figure, the MPT has several data for OP simulation. However, in the next function, SetGROUPVEL(), of the same class, the MPT cannot found in our memory.
Could you check this problem??
