Dear Thomas,
what you want to apply is a biasing technique. But it will not change the energy deposition.
Probably the issue comes from the normalisation (which is the current you expect?) or how you pass the input to ANSYS.
Btw, the penetration depth is 46 um. Luckily, because your USRBIN scoring extends to a depth of only 60 um along the beam direction.
Best, luigi

Hello fluka experts,
At the Fluka course there was a discussion as to artificially increase the cross section for certain cases with a very short bragg peak.
In my case we are trying to simulate energy deposition of 3.6MeV protons into copper. I believe the penetration depth was approx.. 70 micrometers.
When outputting the fluka energy results into ANSYS the temperature results were much lower than expected.
Now finally for my question: can I artificially change the cross section and then rescale the results (and what is the workflow?), or is there (if anything) grossly incorrect in my input that would yield such low energy deposition?
I have attached my input.
Many thanks;
