Dear Cesc,
Thanks for your detailed response.
regarding my simulation I need record the positions where neutrons are produced by (p,n) reaction.
for this purpose, I modify mgdraw (usdraw entry) user routine accordingly.
could you please tell me if it’s right modifications in my mgdraw.f filemgdraw.f (3.6 KB) to record the positions of (p,n) reaction?
best regards,
Qi Ding
