Problem with Ansys Maxwell "current leak to the air"

Click For Summary
The user is experiencing a "current leak to the air" error while simulating an electric plasma arc in Ansys Maxwell, specifically in a tip-to-tip configuration. They have set the vacuum region to 50% from the sides but continue to face the same issue despite refining the mesh. Questions posed in the discussion include the voltage being applied and the effectiveness of the vacuum in the simulation. Additionally, there is a reference to the Paschen Curve, suggesting that achieving accurate results may depend on understanding this relationship. Assistance is sought to resolve the current leak issue in the simulation setup.

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

Thread 'RF magnetic field generation'

Hello! I want to generate an RF magnetic field at variable frequencies (from 1 to 20 MHz) using this amplifier: https://www.minicircuits.com/WebStore/dashboard.html?model=LZY-22%2B, by passing current through a loop of current (assume the inductive resistance is negligible). How should I proceed in practice? Can i directly connect the loop to the RF amplifier? Should I add a 50 Ohm in series? Thank you!
