Error radiation simulation in amino acids

good evening
I have a problem running the script in Flair for Fluka.
I try the simulation of irradiation in amino acids, reconstruction of an article to compare results with the simulation.
I would appreciate it if you could review these files to help me with the problem.

thank you so much.

Thanks Tommaso
I am stay tuned

Dear Alejandro,

I had the time to look at your files. Please find here a few comments:

  • As a good practice (especially when setting up a new simulation), I suggest to keep the PRECISIOn defaults (unless you already know your transport problem very well). Check the defaults in the Manual.
  • Your beam seems large, but this depends on your transport problem. You can check the BEAM card in the FLUKA manual.
  • Your geometry is missing the black hole region and possibly some air surrounding the tank. See this presentation.
  • Material definition: this presentation might help you to cross-check your definitions.
  • Irradiation profile: please read these two presentations about scoring and irradiation profiles.
  • Scoring: you are scoring electron track length density in a detector named “energy”. In case you wanted to score the energy deposited by electrons only, please consult the USRBIN and the AUXSCORE cards.

Looking at your transport problem, I would suggest starting with a Flair example (in Flair: Flair → New → basic) and developing from there.

I hope this helps you start your simulations. Good luck!
