Spectra sampling error RC=255

Running and Runtime Errors
1

Dear Experts,

when I try to run FLUKA using a fluence spectrum that I got from my experimental data, I get the following error message:
Error: “/usr/local/fluka/CERN-FLUKA-spectra-sampling/src/flukahp-spec” executable returned RC=255

Could you please tell me what does it mean?

All the best,

Tiberio

Hi @Tibe68,

Did you have a look in the .out .log and .err files?

Hi Amario,

thanks for answering so quickly.
This is what I get on the .out file:

And this is the .err file:

Hope it helps…

Hallo Tiberio,

it doesn’t. In fact, you did not look at the FLUKA output file (rather at the run output file, of limited interest), which is the one with the same name as the err and log files (i.e. ending with 001, or larger integers). I suspect that the log file is more relevant here, can you please search for it, in /mnt/c/Users/ceccotti/Simulazioni_Fluka/Simulazione_grating/fluka_625 or /mnt/c/Users/ceccotti/Simulazioni_Fluka/Simulazione_grating?

Sorry!
Let’s try again.

Dear @Tibe68,

The log file you posted ends with this error message:

 ERROR: The provided fluence spectrum is not contiguous and has gaps in the energy bin structure. Please provide contiguous bins without gaps!

I think it explains the crash.

Dear Amario,

I think you’re absolutely right. My fault: I should have checked that…
Many thanks again.

Tiberio
