toroidal inductor in cst

i want to simulate ferrite toriodal core inductor.How i can make coil around cylindrical ferrite core in cst.
thanks

You're talking about CST MWS or EMS?
Both have a built-in macro to make some kind of a toroid core and surrounding coil.
IIRC, in EMS, this feature is totally useless because there is nothing you can do with it, i.e., I don't think there's any way to drive the coil you create.
I'm not sure how useful this macro is in MWS...you'd have to experiment with it I guess.

hi,
i was just thinking that you could achieve desired results by doing this:
1. design a helix antenna (i think there is a macro about this) by defining
the required number of turns, diameter etc, , then
2. insert a ferrite body of desired dimensions within the helix antenna
this geometry should behave like an inductor loaded with a ferrite core.
