The non-linear extended MHD code JOREK resolves realistic toroidal tokamak X-point geometries with a G1 continuous flux-surface aligned grid including main plasma, scrape-off layer and divertor region. It is based on robust fully implicit numerics, and includes sheath boundary conditions, resistive wall effects, two-fluid effects and neoclassical flows, kinetic particle models, and further extensions. Main physics applications are the physics and control of disruptions and edge localized modes (ELMs).

- Forks/Renaming: Stick to 'JOREK' or 'JOREK-fork'. Renaming fragments the community—merge upstream!
- Share all own developments based on the code with the community via pull requests upstream to the central repository.
- Include the JOREK Team as co-author in all publications referring to the most recent JOREK overview article as affiliation/footnote. At present this is "For a list of JOREK team members refer to the author list of M Hoelzl, GTA Huijsmans, FJ Artola, E Nardon, M Becoulet, N Schwarz, A Cathey, SJP Pamela et al. Nuclear Fusion 64, 112016 (2024) Doi: 10.1088/1741-4326/ad5a21".
