Intrinsic local Gauss's law preserving PIC method: A self-consistent field-particle update scheme for plasma simulations
Zhonghua Qiao, Zhenli Xu, Qian Yin +1
In order to perform physically faithful particle-in-cell (PIC) simulations, the Gauss's law stands as a critical requirement, since its violation often leads to catastrophic errors…

Local Structure-Preserving Relaxation Method for Charged Systems on Unstructured Meshes
Zhonghua Qiao, Zhenli Xu, Qian Yin +1
This work considers charged systems described by the modified Poisson--Nernst--Planck (PNP) equations, which incorporate ionic steric effects and the Born solvation energy for diel…
