Hi Stefan,

Thanks for pointing out the mistakes in my .inp file. This shows that one
realy OUGHT
to read the manual before rushing into any simulations.

An update on the performance:

FLUKA ( ICARUS defaults): 1487 s

   same problem with similar cuts:
MCNPX: 262 s
GCALOR: 32 s

I am a bit surprised on the difference in speed of these codes. Are there
any benchmarks
on these codes available?

Regards.

Fan
