Hi Alfredo
Thanks for your reply.
For the first part (activating the rflctv.f routine) I do exactly what you
said, (declaring the material a metal) but when I give the value of what3
unphysical (<-99) it gives an error card and the routine still does not
work .
In the case of diffuse reflector: it may be better to consider a mirror
reflection (Specular spike) first, if only the card OPT-PROP with SDUM
METAL is defined, For the optical photons that radiation on the surface of
the reflector, the angle of reflection will be equal to the angle of
radiation, or when we consider a roughness for the surface of reflection,
the angles of reflection will have a Gaussian distribution around a sigma
value (Specular lobe). but my goal is that the optical photons will be
reflected at a different angle from the angle of the radiation each time
(with the same probability at all angles) and necessarily The angle of
reflection is not equal to the angle of radiation. For this purpose, I
modified rflctv.f routine and attached it with the input. Did I modify it
correctly? Why not active rflctv.f routine? Thank you for your prompt reply.
