If so, then am I correct in thinking that the > logical volume which will be replicated inside the mother I have the impression you may have 'confused' concepts of what is a 'logical' volume and a 'physical' volume. I would suggest you to look at the documentation where such concepts, I think, are well defined. Replicas are physical volumes which are -slicing- in equal parts (with no gaps) a given mother volume; this mother volume cannot contain anything else. > 1) Can be a logical volume containing daughter repeated physical volumes placed with > G4PVReplica?

Of course, it can. > 3) Can not be a logical volume containing daughter repeated physical volumes placed with > G4PVParameterised? Don't know what you mean exactly by "daughter repeated physical volumes", but parameterised volumes can have placed volumes inside. > In case 2, if the logical volume to be replicated by G4PVReplica is, say 'A', which contains > a daughter physical volume 'B' that was placed by G4PVPlacement, are there further > restrictions on B? i.e. can the logical volume of B contain daughter physical volumes > placed with G4PVParameterised? If I understood correctly ... in principle you can, but you must know what you're doing in your parameterisation at least ... Cheers, Gabriele ```
