Conical surface with Fluka

I had another question regarding the geometry definition of Fluka. Is there any equivalent to KZ or K/Z (conical surface) of PHITS to Fluka? I could not see any. I had to use the QUA (arbitrary surface) and define the parameters manually.

Dear @Rajarshi,

Depending on your case the use of truncated cones may also be suitable (see the corresponding page in the manual: TRC — FLUKA Manual). Otherwise QUA is certainly an option.
