Hi Anna,

Thank you for reaching out to us and we appreciate your patience.

Please go through the Q3D extractor help document for detailed information on the topics in Q3D extractor. 

If you are referring to the reference and non-ideal ground conductors of the 2D extractor then you can go through " working with conductors in 2D extractor" section in the Q3D extractor help. Alternatively you can go through this Q3D online help link - Ansys Electronics 2022 R2 - Welcome to Q3D Extractor Help.

Best regards,
Praneeth.
