Emu is a multidimensional neutrino quantum kinetics simulation code based on the particle in cell method and parallelized for CPU or GPU supercomputing architectures.

Emu is licensed under the included BSD-3-Clause-LBNL open source license.

Change log for v1.2, referencing github issues & PRs at https://github.com/AMReX-Astro/Emu:

  • Using the new particle shape factor implementation, we now redistribute
    particles only at the end of each timestep instead of at every runge-kutta
    stage (#50).

  • Removed WarpX bilinear filter, since we don't need it to get stable
    evolution. Emu now does not include any WarpX code (#49).

  • Removed WarpX shape factors. Wrote new shape factor implementation in
    ParticleInterpolator so we now can evolve particles within ghost cells (#48).

  • We now determine the shape factor order taking into account both the
    user-specified order and the dimensionality of the problem so we use order
    0 in the directions where the domain contains only one cell (#47).

  • Fixed issue with flavor vector length so we can now run simulations with
    nonzero initial amounts of non-electron flavor neutrinos (#44).
