Continuum model has advantage to provide direct simulation of voltage-current characteristics of ion transport through a membrane which is a multi-scale process.Poisson-Nernst-Planck equations represent a typical one of the continuum models.This talk presents a numerical procedure for 3D finite element modeling of ion transport in a channel.The whole procedure includes mesh generation for protein-membrane system,stabilized FE solution,and result visualization.We are also making effort to provide a web-based simulation service.The method is applied to calculate the current-voltage curves of a few ion channels with wide pores,nanotube simulations with time-dependent(varying)boundary conditions(voltage scanning),as well as to predict the current signals of a DNA-nanopore system for gen sequencing.
