Positioning ellipse ring in Lumerical
I am building a model of ellipsoid rings.
I think there's a bug with the center position once I mark the ring element as ellipsoid: the coordinates (x,y) of the center position of the ellipse are double of the set values for x and y.
Even when I select the element in the GUI - the cross-hair marker shows the set point of the center, but there's no ring there. Instead of (-0.5,-0.4)um, it's at (-1,-0.8)um. It occurs even if "radius" and "radius 2" are the same - as long as I set "make ellipsoid" as true.
- My FDTD version is 2021 R2. I don't know if this happens in previous versions.
- This doesn't happen if the ring isn't ellipsoid, and also doesn't happen for a circle element that I mark as an ellipsoid.
I attached the model file for tests.
