Hi Beatrice,

It seems you have an EXTREMELY complicated region using parenthesis (rconcr)
that expands to more than 100k terms, creating an array out of boundary exception in FLUKA.
I would strongly recommend to optimize that region. Maybe the "easiest" way
 would be to divide the rconcr into many smaller regions either using bound
ing spheres, rpp's or by introducing extra planes, where each subregion
will contain one or a fraction of these "aggragates" objects.

Dear Fluka users,
         I am asking again for a support; I give in attachment an input file:
the geometry is a concrete room around a UC2 target. Near the point of coordinates
(400, 500, 370) a small portion of the concrete shielding is created at a
mesoscale: aggregates and paste. A lot of planes have been used at
the purpose, that is why the geometry is quite complex.
Before I complicated the geometry I had no problems of running, but now, even
if the Geometry editor does not signal any error, I cannot run. I would
like a resolution of 0,1mm in the USRBIN.
Could you please have a check if the problem depends on geometry?
Thank you in advance,
Kind regards

Beatrice Pomaro
