I am trying to get the neutron flux through a shielding material following the fission of uranium. I would also like to be able to change the quantity of uranium to observe how this changes the flux through the shielding.
Can anyone advice on the best example to look at to get me started?
I think you can start by having a look at the example located in /extended/hadronic/FissionFragment. I am not 100% this is what you need but it might take you in the right direction
