Hi Masoometh,
Not sure if this comes too late.
If you are using ion beams in excess of 150 MeV/u (and below 5 GeV/u), you want to use RQMD, thus you must run the executable that you obtain after typing the following in your terminal
$FLUPRO/flutil/ldpmqmd
You can also achieve the same with Flair, if you are more comfortable with that.
As for the necessary number of particles, in order to answer this, you want to run a short simulation and look at the variance of the results, then scale that variance down with the square root of the simulation size, i.e. 100 times more primaries will in average decrease your error bar by a factor 10. As a rule of thumb, at the end of the day you don’t want to use results with relative errors>~30% (this number really depends on particular circumstances), so with that you can compute how many particles you need.

Subject: [fluka-discuss]: DPMJET link
Dear All,
I want to exposed a target made of Bone to a 250MeV/nmu (nuclear mass unit) CARBON beam. Then I want to look the DoseEQ data at three different distances.
Could you please let me know how can I produce the data related to this simulation at the three position. If I need to do this run with DPMJET link? Could you please let me know how I make this link and how many particles is appropriate for doing this run? I can merge and plot data the same as before that I don't work with this link in proton of electron beams?
The file is attached
Regards,
Masoomeh
