Hi Nacira,

Are you using 32-bit executable of Fluka ?

I'm a new Fluka user. I can only build/compile the 32-bit Fluka as I don't have gfortran7.4 nor 8.3.

I have built 32-bit Fluka executables (flukahp) in two machines of 64-bit, one is running Scientific Linux (=Red-Hat) 6 and the other one is Scientific Linux 7.

But in both machines (which are built a bit differently), when I ran on "example.inp", it would stop or get stuck somewhere at cycle 4, after (eg. in one machine)
56000 events. I wonder why this happened ?! It'd finish 3 cycles nicely.

I've tried to put in TIME-CUT what(4) and what(5) (in case there is an infinite loop) but it doesn't help. Setting What(6) doesn't help either.

If I change the RANDOMIZ in example.inp, it'd change where it'd stop (eg. it may stop earlier !) but it can never get past cycle 4.

I've also tried to change -O3 to -O0 or get rid of "-mcpu=... -fexpensive-optimizations" in the compilation. But all these don't help either (it'd still get stuck at
cycle 4 when I run the original example.inp).

I hope the experts can tell us what's wrong :-(

Dear Fluka Experts,

I tried the same thing with simple examples I worked on before but the results were the same.
