Dear Riya,
not sure if it can be fix the warning, but there are several single precision numbers in your source routine.

Try to change all into double precision. For example
STHETA = SQRT(ONEONE-CTHETA**2.0)
->
STHETA = SQRT(ONEONE-CTHETA**2.0D+0)

Cheers, luigi

Dear FLUKA Experts,

While printing x ,y, z in log file , I find the following line at the beginning of the log file.

“The following floating point exceptions are signalling : IEEE UNDERFLOW FLAG IEE DENORMAL.”

The values are printing fine. But I want to know what is the meaning of the above statement and what might be the possible reason for it.

The source file is attached here.

With regards,
