I'm new to Geant4,so maybe my questions are a little stupid.
I have been trying to simulating neutron transport using Geant4,and my model consists of several tubes,whose origins are located in the same point.In order to get relationship between the neutron flux and the radius of different side surfaces,I want to have the upper and lower surfaces of the tubes set as reflecting surfaces(i.e.,a particle track that hits a reflecting surface is reflected specularly.),but I han't found out how to achieve this.
Can anyone help me fix this?
Thank you sincerely.
