drawing a quarter circle using equation based surface in HFSS

Hello everyone
can we draw a quarter circle using equation based surface option in HFSS?
if yes then how ?
Kindly help mee , will be thankful

Hey, I have general solution I just threw together:

X(_u,_v)=circRad*_v*cos(_u*circAngRange+circAngOff set)+xCenter
Y(_u,_v)=circRad*_v*sin(_u*circAngRange+circAngOff set)+yCenter

_u is 0 to 1, _v is 0 to 1, circRad is the radius of the quarter circle, circAngRange is 90 degrees for a quarter circle, and you can rotate the circle to any orientation with circAngOffset. xCenter and yCenter dictate where you want to put the point of the partial circle.

Thanks for asking! If I hadn't hit your unanswered question, I'd have kept searching for a solution rather than thinking about it myself.
