Continuing the discussion from What is the difference between a usrsuwev.f file and a usrsuw.f file?:
Dear FLUKA experts,
Indeed, as you mentioned, I am aware of the reason for the fewer nuclides in the res.lis file. However, there is still an issue that I hope you can address. I conducted a simple calculation of the radionuclides in the res.lis file (under identical conditions), dividing the values in the column (Bq/cmc) by the (Beam intensity). The resulting values matched those in tab.lis file, but there are a few radionuclides whose values do not align. For example, when calculating 8Li, 3.312E+16/6.74E+11 yields approximately 4.9146E+04, which matches tab.lis; however, for 8Be, 7.332E+16 /6.74E+11 results in approximately 1.089E+5 quite different from 5.4393E+04 in tab.lis. 6.74E+11 is the Beam intensity
The contents of res.lis and tab.lis are provided below and a visual representation of the values for 8Li and 8Be is also included,res.lis on the left and tab.lis on the right.
I look forward to your response and thank you.
thanks for your reporting. Could you please send me the input file and the irradiation profile that you used so that I can try myself to reproduce the problem? You can even send them via direct message if you do not wish to upload them publicly.
Thank you for your reply, I will upload the source file here as flair.source-test.f indicates a user-defined SOURCE file.The irradiation time is one year, and the cooling time is only 0 moments.
Thanks for your patience. I ran your simulations with the routine provided to get enough statistics on the nuclide activities. Unfortunately, I cannot reproduce your problem.
My guess is that you are misusing the usrsuwev program: in particular, if you want to obtain with usrsuwev the same numbers that you would obtain with a one-step simulation (FLUKA RESNUCLE + IRRPROFI + DCYSCRE) you should provide as input to the program a file that contains radionuclide yields (FLUKA RESNUCLE without DCYSCORE). If you are using the test15_23.rnc the result would probably be meaningless.
To better frame the issue and better help you, it would be useful to know exactly what you type as input to usrsuwev.
