Hello Dear Fluka Users,
my job working fine with many materials in Target
(Lead, Tungsten, Tantalum, Carbon).
As only I am insert Uranium - as target,
my job finish with error:
skipped
..............
***** Neutron Xsec: ****
**** Group limits, average energies, velocities and momenta start at location 596161, end at location 596784 (I*4 addr.) *****
**** Low energy neutron xsec not found for some media 0 1 ****
I am use Linux version FLUKA: Version of Fluka2002 for Vax, Vms operating system
Any help will be appreciated!
