Good morning, dear teachers. The model has been constructed and there are some computational issues that have been bothering me for a long time. I would greatly appreciate it if you could help me.

- Currently, the neutron flux density I am calculating is based on I1. I would like to know the difference between I 1, I 2, Φ1 and Φ2. What I understand is that I1 is used to obtain unidirectional neutron flux density (/pr), while I2 is bidirectional.

2.I also need to calculate the ratio of the neutron one-way flow to the flux at the exit, which is J/Φ, where the one-way flow should be at an angle of 0 ° to the positive Z-axis direction that I specify. J (Neutron Current Density) how do I calculate that, using I1? how about Neutron Flux Density? Using I2?

3.And I also need to calculate the dose rate of fast neutrons and gamma rays in one of the exit regions. How Do I do that?

There are many problems, and I hope a teacher can help me. Thank you very much!!!
