Question Re: general questions regarding G4LogicalBorderSurface 

Keywords: optical G4LogicalBorderSurface volume G4LogicalSkinSurface
Forum: Processes Involving Optical Photons
Date: 20 Dec, 2006

I'm also trying to set up a solid with different optical interfaces to other parts in GEANT4.

You write that one simply has to place the solids with their dielectric interfaces next to each other.

However, it seems that I need to have the solids overlapping by a certain amount to get a direct transportation from one into the other, without going into the mother volume inbetween.

I read that overlapping volumes are always a bad idea and may screw up the navigation code in GEANT4.

Is there something I could have done wrong here or is it ok to have a slight overlap for optical interfaces?
