Description

Hello,

I get the following error when I switch from JEFF to ENDF cross sections for my simulation.
I tried to put S(a,b) ‘h_water’, but unfortunately none of my attempts worked.

STOP Couldn’t load S(a,b) file=‘h_water’ for Z=1
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
STOP STOP: FLUKA ABORTED

Please upload all relevant files. (FLUKA input file, Flair project file, user routines, and data files)

Dear @Mihaela_Parvu

the thermal scattering laws we have available, only exist in the JEFF-3.3. You can still select ENDF as a library for every material with LOW-PWXS, but you would need to ask FLUKA to load the HYDROGEN S(a,b) from JEFF-3.3, like

Dear Vasilis,

Thank you so much for the very fast response!
