Sum.lis and tab.lis files are missing

Dear experts,

I have been using FLUKA for some time and achieved good results, as shown in the first image. However, after some time, I installed FLUKA on another computer and tried to open the same project. Unfortunately, I encountered an issue: two files, sum.lis and tab.lis, are missing.

It is worth noting that the same project works perfectly on the original computer. Where could the problem lie?

Thank you for your assistance!

Dear @youssef.allay,

I just tested it on my computer, and it works perfectly. I was able to generate the sum.lis and tab.lis files after processing the output files.

I have a few questions:

  • Did you use FLAIR to run and process the files?
  • Did you encounter any error messages during the processing?
  • Could you please share the error files or error messages, if any?

If you have some time, I also recommend uninstalling and reinstalling FLUKA and FLAIR. This could help if the issue stems from the installation process. If you do so, I suggest paying close attention to any error messages that appear during the installation.

Please let me know how it goes.

Cheers,
Samuel

Hello @youssef.allay,
As far I see, it is just that you didn’t process the outputs. Are you sure you did it?
You can check slide 48 of this https://indico.cern.ch/event/1352709/contributions/5822003/attachments/2837036/4957930/03_Introduction_to_Flair_and_basic_input_2024_INTA.pdf

If it doesn’t work, please send me all the files.

Cheers,
Samuel

Dear @sniang ,

Thank you for your help, the problem has been solved. But when reading the output, there is a difference between what I got on the old computer and what I got now. Is there a change in the new update for Fluka?
input: attenu_1.inp (3.0 KB)
old output :
attenu_1_21_sum.lis (305.6 KB)
new output :
attenu_1_21_sum.lis (305.6 KB)

The difference you report is below 2% and may easily be within the statistical uncertainty of the result.
The problem is that your input misses the RANDOMIZe card, hence you pointlessly get fully identical cycles and obtain a null statistical error, instead of a meaningful value for the latter.

Dear @ceruttif,
Thank you its clear now.
