Dear Fluka users

 

 

I have a small question using usyield. I tried to use usryield to score photon dose at different polar angles under the condition of 10MeV electron hitting high-Z target. But except at 0 degree ,the results at other angles shows 0.

  my input file and results are attached. So I wonder if usryield can be used to score the angular dose distribution or something else in my input files is not corrected. Actually I want to study the angular dose distribution around the target.

 If usryield can not do it , are there any other practical methods? Thank you very much.
