Dear Fluka users and authors,
I am a new Fluka user. Our aim is to detect neutrons in a underground
experiment hall. The detector is located in the water pool inside of the hall.
I want to know the secondary particle's performance of underground muons in
rocks, air(a hall) and water pool by Fluka simulation. Suppose the incident
muons with 100 GeV in position of 2 meters inside of rock above the hall. For
those secondary particles, I like to know their the track length, energy loss,
how to decay, .... . Based on a sample file, I wrote a input card. A part of
it is:

Five runs is ended soon with a start of 100. However, the *_sum.lis or
*_tab.lis is zero for most fluencies and errors. A very few of them is not
zero but 99% for errors. I don't know why. hope to get your help!
By the way, what available options is more suitable to show particle's decay
and propagation in the matters, especially for pai and neutron?
Best regards
R.G. Wang
