I have a naive question regarding geometry placement in GEant4; please pardon and point me to relevant sources if it has already been answered in the documentation.
I have 2 different physical volumes having separate logical volumes, A and B. I am trying to place B inside A.
Case 1: Mother volume of both A and B is the world volume?
Case 2: Mother volume of B is A. Mother volume of A is the world volume.
Are Cases 1 and 2 equivalent in terms of the physical processes, interactions, and scoring in the Geant4 ? Or they can lead to physically different results.
Thanks a lot
