Hi,

It looks like you are using a driven terminal solution type instead of a driven modal solution type. Please be advised that these two are different in nature. The integration line to define the current will be available in the driven modal type while reference conductors are used in the driven terminal type.

Kindly switch to the driven modal solution type if you like to use the integration line. For more information on these two different types please refer to Ansys HFSS help document.

Best regards,
Praneeth.
