Planetary SimulationsΒΆ

SWIFT is also designed for running planetary simulations with a current focus on giant impacts, as presented in Kegerreis et al. (2019), MNRAS 487:4.

More features for planetary simulations are in active development so please let us know if you are interested in using SWIFT or have any implementation requests. For example a new equation of state or extensions to the tools for creating initial conditions.

You can find an example simulation in swiftsim/examples/Planetary/ under EarthImpact/. The tabulated equation of state files can be downloaded using EoSTables/

Planetary simulations are currently intended to be run with SWIFT 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.
