Dear Francesco,
Thanks for the suggestions. I implemented your suggestions as far as defining the collision vertex is concerned , i.e., inclusion of BEAM card and HI-PROPE card on top of SPECSOUR card. Also I removed Au material region relevant for my collision vertex. However I got the error on my terminal which looks like
======================= Running FLUKA for cycle # 1 =======================
$FLUPRO/flutil/rfluka: line 359: 13280 Floating point exception(core dumped) "${EXE}" < "$INPN" 2> "$LOGF" > "$LOGF"
Just wondering whether I am missing something in my input file ? My error file and output file are completely empty.
Thanks

Dear Sourav,
1) Shall I have to define Target region of Au material at collision vertex
?
not at all (unless your collisions are supposed to take place in gold instead of vacuum...). You defined the second beam species in the SPECSOUR card, where you have also said that your first beam is made by HEAVYIONs. So you need a HI-PROPE card to specify the HEAVYION nature. And you still need a BEAM card (where you shall put HEAVYION - making redudant your SPECSOUR WHAT(11) setting - and an energy per nucleon exceeding 100 GeV/n for transport initialization purposes).
2) Which scoring card should be used in order to retrieve kinematic
information of produced particles and nuclear remnants after H.I. collision
? So far I have used “USRYIELD” card.
USRYIELD does not work yet for the SPECSOUR collision event. You can inspect the properties of the products by customizing the usrein.f routine - which is automatically called before source particles start to be transported - in order to look at the FLKSTK content (to this purpose remember to add the
INCLUDE '(FLKSTK)'
statement).
Cheers
Francesco

Dear Fluka users,
I have been trying to simulate Au+Au collision at C.M. energy of 200
GeV/nucleon using DPMJET3 within FLUKA framework. For defining the colliding
beam I used SPECSOUR card with PPSOURCE type. I am mostly interested in
getting the kinematic variables (px, py, pz, energy , pid etc) of the
particles after the collision and also the remnants of the nuclei after
collision. My questions are
1) Shall I have to define Target region of Au material at collision vertex
?
2) Which scoring card should be used in order to retrieve kinematic
information of produced particles and nuclear remnants after H.I. collision
? So far I have used “USRYIELD” card.
Any suggestions will be of great help.
Please find the attached input file for FLUKA and the output file after
executing FLUKA using the command $FLUPRO/flutil/rfluka -e flukadpm3 test
Any suggestions will be of great help.
Thanks
