Air-filled Cavity in Cable Insulation

Please login with a confirmed email address before reporting spam

I have made a simple cable and insulation with a circular air-filled cavity in the insulation.

When I perform the stationary study, the electric field through the cavity remains the same, regardless of its diameter, which is not accurate.

How can I implement a formula to the void specifically, such that the electric field through the void also depends on the size of the void?
