Planetary Simulations

SWIFT is also designed for running planetary simulations such as of giant impacts, as introduced in Kegerreis et al. (2019), and any other non-planetary simulations with more complicated equations of state and/or multiple materials, etc.

Active development is ongoing of more features and examples, so please let us know if you are interested in using SWIFT or have any implementation requests.

You can find an example of creating initial conditions and running an impact simulation in swiftsim/examples/Planetary/ under DemoImpactInitCond/ and DemoImpact/. Check out their README.md files for more info. The tabulated equation of state files can be downloaded there using EoSTables/get_eos_tables.sh.

To run planetary or similar simulations, SWIFT should be configured to use the planetary hydrodynamics scheme and equations of state: --with-hydro=planetary and --with-equation-of-state=planetary. These allow for multiple materials to be used, chosen from the several available equations of state.
