I was trying to do a simulation with the human_phantom example concerning lungs. Reading the logs, I found that the physical lung is not present in the simulation. I thought maybe the lung hasn’t been implemented or something, but after reading the source code, I saw that the lung building function is present in the source code. I started wondering then why isn’t it being constructed, and found that in the src/G4HumanPhantomConstruction.cc, the builder->BuildLeft/RightLung has been commented out. And the lung shows up in the simulation after uncommenting this.
Is there a specific reason for this to be commented out?
