ETAP GROUNDING GRID SYSTEM BY FEM

[LDKGR]

Dear all,

I'm designing grounding system for my project now. My plant area is fairly big (about 4000m underground mine).
I am a new ETAP user. I am trying to design the system with FEM method. The grounding system of the mine consists of rods and a common PE insulated conductor. So I would like to know if there is a way to simulate the PE conductor (it's path is above ground).

Thanks
