I'm working on a very basic setup to activate cobalt 59 with neutrons emitted from californium 252. MCNP is giving me the following warnings: warning. photonuclear physics may be needed (phys:p)...

Actually, it seems to be wrong for me as well, but I'm following the procedures to validate the model. For the part of detector my conclusion was that he used ring detector tally f5 instead of defining it in a separate cell. another thing is the EBS neutrons the flux doesn't differentiate...

For the part of BPE and PE I switched them in my reply. They are written correctly in the input file and the image I attached. I want to see the change in the flux with and without the TNT, but in the output flux doesn't change. It gives me 1.5*10^-3 with the TNT and 1.49*10-3 without it. I...

Thank you for the reply, I edited the part of the source, and it works now but still gives me a tally warning " warning. tally 4 tfc bin did not pass 2 of 10 statistical checks. warning. 1 of 1 tallies did not pass all 10 statistical checks. warning. 1 of 1 tallies had bins with large relative...
