As far as I know It is not possible to define a torus with FLUKA. None of
the existing body types ( corresponds to a torus.
Note also that a torus is a quartic (not a quadric) so I cannot be even described by the generic QUA body.
A way around this is to approach your torus by a series of stacked rings of different width or by a string
of cylinders at small angles with respect to the neighboring one. Also, I remember that Alberto Fasso had
developed and implementation of the torus for FLUKA.

If yes, what is the input card ?

Thanks for answering.
