Hi, I have a simple question. Let's say we have a voltage source and ground with air in between them. When this voltage source creates an ambient electric field directed towards the ground and the field strength exceeds the air breakdown threshold of approximately 3 MV/m (at standard temperature and pressure), the air becomes conductive and starts to conduct electricity.

Is it possible to simulate this scenario and visualize the breakdown of air? I explored a CST project called "3D ESD Generator Model (Air Discharger)" in both the CST help forum and the CST software, but I couldn't find any visual representation of the air breakdown. If someone could shed light on this aspect, it would be greatly appreciated. I just want to capture (say some kind of glow or some visual aspect) of when the air starts conducting at some particular condition. Please help me out on this topic. Thanks.
