一类含时Poisson-Nernst-Planck方程的时间自适应计算

Abstract

Abstract: The time-adaptive finite element method based on adjacent time steps was used to solve a class of time-dependent Poisson-Nernst-Planck (PNP) equations, which accelerated the efficiency of long-term numerical simulations for solving two-dimensional PNP equations containing multiple ions. Numerical experimental results show that the method can effectively accelerate computations in both numerical formats and is effective for long-term numerical computation of PNP equations.

Key words: Poisson-Nernst-Planck equation, finite element method, time-adaptive, numerical computation
