Streamer Simulations With Dynamically Adaptive Cartesian Mesh

Streamers appear in gases, liquids, and solids due to impact ionization in high electric fields near streamer tips. Dynamically adaptive mesh enables high resolution of sharp streamer fronts with a large dynamic range and a minimum number of computational cells. We present results of computational experiments utilizing dynamically adaptive Cartesian mesh for multiscale resolution of streamers near curved electrodes in 2-D and 3-D geometries.
