Description

Dear FLUKA Experts,

I am currently running a simulation of neutron interactions with deuterated liquid scintillator. In this process, I utilized the stuprf.f user subroutine.

Unfortunately, the simulation encountered an issue during execution. I have checked the corresponding .log and .out files for troubleshooting, but no .err file was generated, which makes it difficult for me to pinpoint the root cause of the problem.

Given this situation, I suspect that the error may be related to the input settings in my .inp file—specifically, the Residual Nuclei card or the configuration of the Evaporate physics model.
Could you kindly offer some guidance on this issue? Any advice or suggestions would be greatly appreciated.

Thank you very much for your time and assistance!

Best regards,

Yiteng

The error is reported in the .log file and is due to the incomplete definition of the Deuteron elemental material in the .inp file, where both atomic number (1) and mass number (2) are missing.
(In the absence of the latter, natural isotopic composition is assumed, but the first must be input, except for a compound, whose definition must be completed by a respective card).

Also, the fact that you have installed an Unknown FLUKA version is somewhat problematic.

Thanks a lot.It is worked now!
