PHANTOM: A smoothed particle hydrodynamics and magnetohydrodynamics code for astrophysics

About

Phantom is a fast, parallel, modular and low-memory smoothed particle hydrodynamics and magnetohydrodynamics code developed over the last decade for astrophysical applications in three dimensions. The code has been developed with a focus on stellar, galactic, planetary and high energy astrophysics and has already been used widely for studies of accretion discs and turbulence, from the birth of planets to how black holes accrete.

Emmy Noether Women in Computational Astrophysics Prize Talk

In 2023 we implemented a new prize talk to recognise and encourage contributions from early career researchers

The 2nd prize talk was given by Anna Childs from Northwestern University

Core values

Open

Phantom is free to use, download and redistribute under the terms of the GPLv3 license. We also welcome contributions to the code via the GitHub repo. Just get in touch!

Modular

Phantom is built in small, re-usable modules, making it easy to add new physics to the code.

Modern

All modules are written in modern Fortran and we enforce strict adherence to the very latest Fortran standards.

Lean

We strive for a low memory, high performance code with as few options as possible. It should "just work". Phantom is not a code for testing algorithms, it is a "take the best and make it run fast" production code for astrophysical simulations.

Tested

Phantom contains a comprehensive testsuite that runs on every pull request before it is merged to master. We strive to continually increase the scope of the tests to cover every aspect of the code.

Re-useable

We aim to never repeat code.

Download

Phantom is free and open source, and may be obtained from the git repo. All we ask is that you cite the Phantom paper and other relevant methods papers in scientific publications and keep the name "Phantom" in derivative works so as not to misrepresent the code as your own. We also welcome and encourage contributions to the Master code rather than ending up with many divergent copies.

Although the above versions are listed as 'Stable', the Master branch on the git repo should always be stable since Pull Requests are only accepted into the Master branch once they have passed the testsuite and been proven to not break the code.
