Calculating inelastic heavy-ion cross sections

Dear Fluka experts and users,

I have just recently installed Fluka, and am a complete beginner. I aim to calculate inelastic cross sections in heavy ion collisions such as carbon beam, incident on a graphite target block at momentum beyond 10A GeV/c. Is there an example input file or is there a simple way to understand to create an input file for such interactions, outputting cross-sections in mb?

Best,
Neeraj
