@hhollenb Your volume surface selector PR should close this issue 🎉

@wdconinc There's no immediate action required here, but if you have a representative GDML you can send us (email, slack, upload here), it'll make it easier for us to characterize/test...

That's great, thanks so much for the links!

Sandro has provided an event file `ALICE_Pythia8_pp_1000events.hepmc` and geometries. We'll see if we can run it, and see if we can extract an expensive subdetector.

Notes from today's meeting (compiled an hour later so hopefully I remember the important bits): - Cherenkov is neglected in current simulations; it's only a few percent, and the detectors...

@whokion You can forward this issue page to Erica with a link to our (almost current) status? https://indico.cern.ch/event/1466097/contributions/6216512/attachments/2965789/5217806/celeritas-optical-photon.pdf

To get from DUNE: - Physics list construction (done through larsoft: larsim, larg4) - GDML export - Sensitive detector definitions Ken to send primer of running larsoft event which should...

From Matthew Green: > To start, we simulate scintillation photons produced in liquid argon, in which we approximate the blue curve in the figure as a gaussian distribution centered at...

## Notes from 9/22 meeting with Ian: Likely challenges: - CAD geometry for structural scintillating plastic components (PEN plates) will require tesselated mesh support - Full Geant4 mode stores full...

Notes on today's meeting with @seriksen: - LZ currently uses optical maps due to prohibited cost of inline optical tracking (Would very much like to do optical photons inline to...
