This code provides Finite Element solvers for electrochemical transport. Both continuous Galerkin (CG) and discontinuous Galerkin (DG) schemes are provided. The DG scheme for electroneutral Nernst-Planck is described in Roy et al., 2021. The CG scheme using SUPG for the advection-migration term.
The following transport mechanisms are available: diffusion, advection, electromigration. EchemFEM supports both non-porous and porous cases. The ionic potential can either be described using an electroneutrality constraint or a Poisson equation. In the porous case, the electronic potential can be described by a Poisson equation.
