Zero error with resnuclei

Dear Fluka Experts,
I run a simulation to study the activation in air with the resnuclei card. The simulation includes 10 cycles.

Unfortunately, the output gives me results with zero uncertainty, as you can see in the sum.lis and tab.lis files. I have tried to run the simulation several times but the result does not change.

Punita_attivazione.inp (6.9 KB)
Punita_attivazione_23_sum.lis (6.3 KB)
Punita_attivazione_23_tab.lis (14.0 KB)

What could be the reason?

Thank you,

Corrado

Dear Corrado,

you are missing a RANDOMIZE card in your input file. Without this card, the seeds for each cycle are identical, hence the results are identical and the error is therefore zero.

Kind regards,

Markus
