Unconditional positivity-preserving and energy stable schemes for a reduced Poisson-Nernst-Planck system

28 Sep 2019 Liu Hailiang Maimaitiyiming Wumaier

The Poisson-Nernst-Planck (PNP) system is a widely accepted model for simulation of ionic channels. In this paper, we design, analyze, and numerically validate a second order unconditional positivity-preserving scheme for solving a reduced PNP system, which can well approximate the three dimensional ion channel problem...
