The Open FUSION Toolkit (OFT) is a suite of modeling tools, and their underlying finite element framework, for problems in plasma and fusion research and engineering in arbitrary 2D and 3D geometries. The underlying framework and its component tools support the use of variable order finite element methods on unstructured tetrahedral (triangular) or hexahedral (quadralateral) grids.

NOTE: This project is current in a beta status as the transition to a fully open source code, including associated documentation and examples is completed. For more information see v1.0 release status for more information.

The suite currently includes the following tools:

• TokaMaker: Axisymmetric statice and time-dependent ideal MHD equilibria

• ThinCurr: Inductively-excited currents in the thin-wall limit

• MUG: Time-dependent nonlinear (linear) extendend MHD

• Marklin: 3D force-free ideal MHD equilibria

Binaries are available for Linux (x86) and macOS (x86 and arm64) for each release on GitHub. The framework and its components can also be built from source using the instructions provided on the wiki.

To use the python interfaces add the python directory for your installation to your PYTHONPATH environment variable.

Detailed documentation is available online and is also included in the binary packages at /path/to/oft/install/doc/Documentation.html (please note /path/to/oft/install is a placeholder for the actual install path).

See CONTRIBUTING.md for information on how to contribute.
