Loop area when a conductor in finite element space is closed with circuit element

Dear all,

My question is pertaining to loop area in Altair FLUX 3D. I have a solid conductor of 100mm length in 3D finite element space. Now, In electrical circuit space I grounded this solid conductor with a ground element.

What is the loop area of this setup?

please advise.  (Kindly refer image for more illustration)
