Dear fluka experts,
I have some doubts regarding mainly measurement units…
[1] What do the maximum, minimum, and int values mean in the graph plot? are the maximum and minimum values of what exactly? Do they have a unit of measurement?
[2] What do the x and y axis represent in each case? USRTRACK, USRDUMP and USRBIN in the attached images.
Thank you very much!!

Thank you for your question. If possible, it would be good practice to share also the *.inp or *.flair files that you have used to obtain the plots, but already looking at them and answering your questions:

For USRBIN, you are scoring a 3D mesh (200 bins in each direction). The min/max correspond to the min/max value that you record in your 3D mesh (excluding 0 values). The Int should correspond to the integrated 3D mesh value. In your case it is lower than your min/max because you have many 0 bins in your mesh. The unit of measure depends on what you are scoring.
I assume you are scoring 4-HELIUM particle fluence (but I would need the *.inp file to be certain), hence the unit would be in particles per cm2 per unit primary weight, according to note 8 of the manual.

For the:
a) USRBIN plot: x and y are the spatial dimensions (in cm).
b) USTRACK plot: x is particle energy (in GeV) and for y, it depends on what you are scoring, but I assume fluence again.
c) USRDUMP: y is the counts, but I cannot see what x is without the *.flair file)

Thank you very much for answering me!
I THINK it is fluency for usrbin. I have attached the files now, and userdump I really couldn’t understand. 1kev.flair (5.1 KB) 1kev.inp (3.4 KB)

Indeed, for USRBIN you are scoring particle fluences, and similarly for USRTRACK.

The USRDUMP you have activated scores every particle interaction, and requires more post-processing to extract the information from it, depending on what you wish to explore.
