Dear expert
Currently, I want to compare the impact of bilateral and unilateral target shooting on the yield of nuclides. When conducting bilateral target shooting, I encountered the following error message
It ended with an error after I added the PHYSICS card
However, the previous FLUKA expert told me that this card was outdated and should be deleted in any case
I need your help. Thank you
Dear Zhiyu,
indeed, the use of IONSPLIT card for Deutron treatment is obsolete, you should remove it.
To be able to run the simulation, you need to use the flukadpmexecutable, which includes the rQMD and DPMJET event generators.
Cheers,
David
Dear expert, I understand your meaning, but I don’t understand why such an operation is not necessary when shooting from one side. Secondly, I don’t know how to use the flukadpm executable. I haven’t found any relevant tutorials in the forum. Could you please tell me how to operate it or if there are any related tutorials? Thank you!
Dear Zhiyu,
This is not related to the scoring used, but to the improvement of the deuteron treatment in FLUKA.
Please look at slide 32 of
to see how to change the FLUKA executable.
Cheers,
David
A likely reason is that in one case you have the PHYSICS/COALESCE card, requiring the flukadpm executable, and in the other case you haven’t put it.
Thank you for your guidance. I successfully ran Fluka. May you have a good mood every day in the days to come.
This does not explain why in one case flukadpm is required and in the other it is not. If you want to clarify the issue, please upload the two input files entirely.
Thanks. I shall acknowledge that your screenshots above were actually already explaining the different behaviour: for case two (top screenshot, no BEAM card) the code takes the default BEAM card values (protons of 200 GeV/c momentum) for initialization purposes and concludes that coalescence may generate fragments (A>1) requiring RQMD/DPMJET to interact. Thereby, it stops and asks to use flukadpm (it doesn’t if you have PHYSICS/IONSPLIT, as an alternative to a proper interaction, but you shouldn’t, as already pointed out). In fact, you have 40 MeV electrons (as from SPOTBEAM), but the flukadpm requirement is unfortunately not lifted.
In the other case (one, BEAM card with 40 MeV electrons), the above requirement rightly doesn’t apply.
Thank you for your guidance.
