About

MCFOST is a 3D continuum and line radiative transfer code based on an hybrid Monte Carlo and ray-tracing method. It is mainly designed to study the circumstellar environment of young stellar objects, but has been used for a wide range of astrophysical problems. The calculations are done exactly within the limitations of the Monte Carlo noise and machine precision, i.e. no approximation are used in the calculations. The code has been strongly optimized for speed.

Contributing

We welcome contributions, including (but not limited to):

1. Code, via pull request. Please read the developer section of the user guide for guidelines. We use the pre-commit framework to automatically fix some coding bad practices. It is recommended to install pre-commit by running the following commands from the top level of the repo

python3 -m pip install pre-commit
pre-commit install

2. Documentation, also by pull request. Docs can be edited in the docs/ directory of the main code.
3. Suggestions for features or bug reports, via the issue tracker. Please file bugs via github rather than by email.
