Complex geometry

Dear Fluka experts,

I’m trying to make a model of scintillation fiber which is winded up around cylinder. Is it possible to create such geometry in Fluka?

Thank you in advance

Dear Alexy,

unfortunately complex geometries, like a torus, or spiral cannot be defined with one card.

One possible solution is to approximate your fiber with, sections of cylinders.
If the fiber is winded closely, maybe an outer cylinder could work as well.
