Hi.
I'm trying to solve the electric double layer structure using Nersnt-Planck eqn and Poisson eqn rather than Poisson-Boltzmann eqn.
My domain is pallel plate of which height is nanometric, typically ~10nm.
However, my model failed to converge.
Sometimes, converge is succed. But that result is not coincided with analytical solution.
What is the problem?
Is there anyone solved this problem?
