Hello,
I would suggest you change the line:
LOW-MAT 7 7.0 14.0 293.0 NITROGEN
with :
LOW-MAT 7 7.0 -2.0 293.0 NITROGEN
The new FLUKA version includes a change for the LOW-MAT card for the nitrogen.
Cheers,
Manuel

Subject: Low energy n xsec not found for some media
Hello, after I recompiled my executable with new FLUKA distribution I am
getting the following error:
**** Low energy neutron xsec not found for some media 18 19 ****
After this message the execution stops.
Piece of the input file with the material description is attached to this
message. You can see that I do not use FLUKA materials 18 and 19 (that is
Uranium and Plutonium). If the numbers in the error message correspond to
the material number from n xsec table, then these are Argon and Potassium
that I am using but they are described explicitely with LOW-MAT options.
I checked that I am getting this error also with an old input file that
was working properly with the previous FLUKA release.
Could you please comment. Lev.
