[chaplajay]

hello

can u help me to design circular spiral in CST 2011 & HFSS 11.11?
i can not design in this kind of software...
plz help me out...

To create a spiral in CST try the analytical curve function.
Set x: R*cos(t)+t*cos(t) y: R*sin(t)+t*sin(t) z: 0 or t (if you want it to be a helix)
Then set t to go from 0 to x*2*pi, where x is the number of times it will spiral around.

Hope this helps!
