Dear Fluka Experts and especially to Paola Sala, Francesco Cerutti,
Vasilis Vlachoudis,Florian Sommerer, Andrea Mairani,

As I ask in 9th FLUKA course at BARC, India that what to do if the FLUKA
stack is full ?
  When I was running the input for estimating the neutron fluence from
6MeV electron source. I faced the problem of FLUKA stack is full. While
running upto 6 cycle it runs and at 7th cycle after completing 480000
histories it shows the following error in .err file

because of missing room in FLUKA stack ***
  **** Photonuclear interaction not performed

Because of this the fluka run stops.

Before this also I have got the same error. May be I am wrong but I
thought that this cause because of I have given very low number (2e-6) in
biasing of inelastic hadronic interaction length of photon using LAM-BIAS
option. So at that time I changed the biasing option in lambias card and
carry out the run for next runs, then it runs. So I never sent the files
and error to FLUKA discuss. But as discussion in fluka course I understand
that I should share such things.

Please correct me if I am wrong somewhere. Also tell me what to do in such

Thanking you.
