I have added in the ASSIGNMAT cards, but I am still seeing the same behavior from the code. I have attached the updated input file.
Thanks for your time,
Justin

Subject: Re: [fluka-discuss]: Optical Photon Example - Cherenkov
Dear Justin
You forgot to assign materials to regions. It could be done by adding ASSIGNMAT card.
Cheers,

Dear FLUKA experts,
I am trying to understand generation of optical photons, and attempting to recreate the code from the Cherenkov example in section 12.2.3 of the FLUKA manual. I have typed up the code, but I am not seeing any photons generated. The code runs (suspiciously quickly for a large number of histories) , but doesn’t appear to do anything. Any thoughts on what the problem could be? Code attached
