Abstract. Drift-diffusion models are useful for studying ion transport in open protein channel systems over time
scales that cannot be resolved practically by detailed molecular dynamics or quantum approaches. Water is treated
as a uniform background medium with a specific dielectric constant and macroscopic current flow is resolved by
assigning an appropriate mobility and diffusivity to each ionic species. The solution of Poisson's equation over the
