Dear Beatrice,
Running your input file, one gets following error message:
*** Too many terms in parenthesis expansion ***
*** Execution terminated ***
I think the message is quite self-explaining. The issue lies in the definition of the second zone of the rAir region. As a good practice, I would try not to use too many parenthesis (you can equally define the geometry without using any parenthesis at all). Also note that if you have too many bodies in a zone definition this can also slow down the simulation. It is better to have more zones with fewer bodies than to have one zone with many bodies.
Besides, on the EMFCUT card you set the production cuts for e-/e+ and photons to 0. Note that physics models are no longer applicable at very low energies and one should respect the minimum values recommended in the manual. I quote:
"The minimum threshold energy for transport and production of photons is 100 eV. For electrons and positrons, it is 1 keV."
Cheers, Anton

Subject: [fluka-discuss]: Fwd: Gamma-ray experiment
Dear Fluka experts,
I am trying to reproduce an irradiation experiment due to gamma-rays from a Cobalt60 source.
I am using Flair. I can not run the input file because the 001.out file stops before reading regions, while the file .out gives a generic error message (that I am reporting here below):
Dir: /home/flupix/Desktop/Prova
Cmd: /usr/bin/nohup /usr/local/fluka/flutil/rfluka -e /home/flupix/Desktop/Prova/Prova.flair -M 2 Prova
$TARGET_MACHINE = Linux
$FLUPRO = /usr/local/fluka
Initial seed copied from /usr/local/fluka
Running fluka in /home/flupix/Desktop/Prova/fluka_2030
======================= Running FLUKA for cycle # 1 =======================
/usr/local/fluka/flutil/rfluka: line 359: 2058 Aborted (core dumped) "${EXE}" < "$INPN" 2> "$LOGF" > "$LOGF"
No .err files are produced yet, since the analysis stops before.
I am attaching here my input file. Would you tell me what I am doing wrong, please?
Thank you in advance,
Best regards,
Beatrice Pomaro
