Dear All,
I need a geometry represented by a pack of thin hexagonal silicon
plates. There is no tool in FLUKA to construct a hexagonal prism,
therefore I construct each hexagonal plate (actually a prism with a
small height) by eight generic half-spaces (PLA). To define such a
geometry I have to use name-based free-format notation together with
parentheses to define vacuum region. My construction works very well
with 1,2,3 and 4 plates in the pack, but it does not work with 5 and
more plates (I actually need 60 plates as a minimum). A task with more
than 4 plates produces segmentation violation error after 5-10 seconds
of normal running. The error message about segmentation violation
appears in the log-file, not in the console:
--------------------------
Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.
Backtrace for this error:

-----------------------------
Can you help to overcome this problem? I send two collections of files,
for normal work with four plates and for error with five plates.
Thank you in advance,
Alexander
