I am a very new user of Geant4 and am learning all of the uses and capabilities of the program. I am currently using version 10.07.00 and am running into trouble trying to turn off Optical Photon Processes. Specifically the absorption process. Even more specifically in the GUI, as this is the only way I was instructed how.
I am trying to observe the Cerenkov photons created, but it appears that the material is absorbing all of the photons. I have tried to increase the absorption length to a much higher value but run into segmentation faults. So, my next idea was to turn off absorption altogether. I will try to attach a few photos regarding my error codes as well as the problem that I am facing. Any insights would be greatly appreciated.
This is the code I am running followed by the error that I am receiving.
/process/optical/processActivation OpAbsorption false
illegal application state – command refused:“/process/optical/processActivation OpAbsorption false”
