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-Planc k(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.
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.
