Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|

You are using "groundteflonair" which if I remember correctly is a surface where the crystal is wrapped with teflon and has a small air gap. You'll define this to be the surface of all sides of one of your crystals except the one side with the read-out. Optically, the glue that binds the crystals together is irrelevant.

The 'envelope' is as wide in lateral dimensions as the crystal. In lenght - the direction to which you have the read-out - the envelope is as long as the crystal + readout/detector-volume. You place envelopes in the array next to each other without space.

As I already said, do not worry about 'same material' on both sides when your surface is not dielectric_dielectric or has a G4OpticalSurface. You are using dielectric_LUT and you are using a G4OpticalSurface.
I attach code - a modified OpNovice example - that was provided to me by Martin Janecek from Rapiscan Laboratories as a guide.
