Production of cross sections of Li, Be, B in channel of 12C+p

Scoring
1

Dear Experts,

I am simulating the carbon beams with a proton target, tracking the cross sections of Li, Be, and B. But my simulations are always stopped by errors:

/Users/jiangqiqi/Downloads/fluka4-4.1/bin/rfluka: line 376: 6166 Floating point exception: 8 (core dumped) “{EXE}" "{INPF}” > “${LOGF}” 2>&1
Error: “/Users/jiangqiqi/Downloads/fluka4-4.1/bin/fluka” executable returned RC=136.

I think my USRYIELD card might lead to problems because the lldb output information:

This version of LLDB has no plugin for the fortran90 language. Inspection of frame variables will be limited.
Process 5471 stopped

  • thread #1, queue = ‘com.apple.main-thread’, stop reason = EXC_ARITHMETIC (code=EXC_I386_SSEEXTERR, subcode=0x1933)
    frame #0: 0x0000000100742fc0 fluka`master.0.usryld_ at usryld.f:1114:132
    Target 0: (fluka) stopped.

I don’t know the real problem and could you help me check the .inp file? Many thanks in advance!

Best,
Qiqi

Dear Qiqi,

you need to specify the ranges of the quantities. Some of them don’t have a default values. For details see the manual: 7.22.94. USRYIELD — FLUKA Manual

Cheers,
