[fluka-discuss]: Fluka errors with neutrons at low energies

Dear FLUKA experts,

I need tu run a series of simulations from 0.1 meV to 20 MeV with
neutrons. I found out that when I put the neutron energy from 0.1 meV to
1 eV a lot of run crashes giving this error:

FLUKA/flutil/rfluka: line 361: 3976400 Floating point exception(core
dumped) ${EXE} 2> $LOGF > $LOGF

This do not happens anymore from 1 eV to20 MeV, with no run crashed.

What could cause this error? I discovered that this only happens on the
server and not in remote. I tried both the old fluka version and the new
one. For my simulations I have to activate the coalescence and the
evaporation using the ldpmqmd compiler. Could it cause some problems at
low energies?

Best regards, Alessandro Calamida.
