Decay following a perturbation of the K+ concentration in a PNP simulation.
We consider a simple 2D example with two ions, K+ and . A: Initial conditions for the two ions. B: Concentrations in the center point as functions of time. C: Charge density,
, in the center point as a function of time. D: The equation terms,
and
, of (2) in the center point as functions of time during the first 4 ns of simulation (left) and after 4 ns (right). We use
