Problem with Ansys Maxwell "current leak to the air"

[jdiab11]

Hi everyone, I am currently trying to simulate an electric plasma arc (tip to tip configuration), same as the one shown in the picture here, I made the vacuum region such as it is 50% from the sides, and touches the current in and out region
However when I run the analysis, I am getting the following error "current leak to the air"
Anyone can help me figure out what the issue might be and how to fix it? I tried a more refined mesh too, same issue
any tip is appreciated I am still new to maxwell

Welcome to PF.

What voltage are you applying? How hard of a "vacuum" are you using in the simulation? Are you trying to get results similar to the Paschen Curve?
