optical photons problems

Hello everyone,

I'm working with optical fibers and I need to score photons
transported in the limit angle. The fibers extend along the x-axis so
I control values of Cxtrck ("direction cosines of the current
particle") contained in the TRACKR common. I realized that most of the
optical photons go through the regions while maintaining the same
direction cosines at the boundary crossing and they move to the next
medium (is it right?...it seems to me that the laws of optics are not
taken into account).
Currently I produce optical photons (Fluka id = -1) and use the
routines source.f, abscff.f, dffcff.f, rfrndx.f and mgdraw.f. Where am
I doing wrong? Should I add something?

Thanks, Stefano
