The DG scheme for electroneutral Nernst-Planck is described in [Roy et al., 2023](https://doi.org/10.1016/j.jcp.2022.111859). The CG scheme uses SUPG for the advection-migration term.\n\nThe 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.\nSome finite size effects are also implemented. For example, the generalized modified Poisson-Nernst-Planck model (GMPNP) is used in the examples of [FireCat](https://github.com/LLNL/firecat), coupling in with a microkinetics model.\n\n\nLLNL-CODE-837342\n\n## Documentation\n\nUser guide and API documentation can be found here [documentation](https://software.llnl.gov/echemfem/index.html).\n\n## Installation\n\nPlease install the open-source finite element library [Firedrake](https://www.firedrakeproject.org/download.html).\n\nTo install EchemFEM, simply run the following in the parent echemfem folder:\n```\npip install -e .\n```\nThe documentation has more details about installation and running the code.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fllnl%2Fechemfem","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fllnl%2Fechemfem","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fllnl%2Fechemfem/lists"}
