I am using a HP physics list and after several events I have to modify the materials in my geometry. I am using an UpdateGeometry() function in my DetectorConstruction. However this results in the run being aborted.
It happens only if I use the HP lists, so I believe that the G4NDL cross-sections data have to be "loaded" again after the geometry modifications. I would be very grateful if you could please let me know how I could do that.
