摘要: 基于相邻时间步的时间自适应有限元方法求解一类含时Poisson-Nernst-Planck(PNP)方程, 以加速求解含有多种离子的二维PNP方程的长时间数值模拟效率. 数值实验结果表明, 该方法在两种数值格式下都可以有效加速计算, 对于长时间PNP方程的数值计算有效.

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
