Scoring in thin layer

Dear FLUKA and FLAIR experts,

I want to run a simulation where I have a thin layer of 10^(-5) meters of silicon touching a thick layer of tungsten.

I’m having trouble when I try to do very very thin scoring. Is there a way to circumvent this problem? or I just have to accept this limitation?

Could you point me some extra considerations that I should have in mind at the moment of performing the simulation?

I attach my .inp and .flair files.

Thank you in advance,
Marcelo

Dear @marcelo.vidal,
Could you please explain better what kind of troubles you’re having?
