Athelas: Astrophysical Transients with Hydrodynamics and Emission using a Lagrangian Arbitrary order Scheme

Athelas is a modern radiation hydrodynamics code for simulating astrophysical transients.

Key Features

• Gray two moment radiation transport

  • Fully implicit and IMEX treatments

• Lagrangian hydrodynamics

• High order discontinuous Galerkin methods

• Fully coupled implicit-explicit time integration

• Radioactive heating from Nickel and Cobalt decay including gammas and positrons.

• Saha ionization with feedback into the equation of state

• Shared memory parallelism with Kokkos

• A thermal engine for artificially driving supernovae.

• A modular package system that automatically threads new physics into the timestepper.

Athelas is open source developed as a tool for the community. Check it out on GitHub!
