Hi everyone,
I am a relatively new user. For the first time, I am trying to implement a geometry with GDML. I am able to import the GDML geometry. There are multiple objects in that geometry including my sensor. Now I would like to tell Geant4 which of these objects is the sensor. I cannot find any reference guide or anything for how to use GDML. All I find is how to load the whole geometry into Geant4 which is pretty easy and it works just fine.
I already have a working simulation where I was creating the geometry inside Geant4. I have a class that handles the detector (response, output, etc.). So, I just hand over the physical volume that I create in Geant4 to that class. Now I want to hand over the physical volume from the GDML file to that class instead, but I don’t know how.
Any information or reference to some sort of reference guide for GDML in Geant4 would help. Thank you!
