thornado+Flash-X: A Hybrid DG-IMEX and Finite-Volume Framework for Neutrino-Radiation Hydrodynamics in Core-Collapse Supernovae
Eirik Endeve, Vassilios Mewes, J. Austin Harris +15
We present neutrino-transport algorithms implemented in the toolkit for high-order neutrino-radiation hydrodynamics (thornado) and their coupling to self-gravitating hydrodynamics…
Preparing Nuclear Astrophysics for Exascale
Max P. Katz, Ann Almgren, Maria Barrios Sazo +7
Astrophysical explosions such as supernovae are fascinating events that require sophisticated algorithms and substantial computational power to model. Castro and MAESTROeX are nucl…
The Castro AMR Simulation Code: Current and Future Developments
M. Zingale, A. S. Almgren, M. Barrios Sazo +7
We describe recent developments to the Castro astrophysics simulation code, focusing on new features that enable our simulations of X-ray bursts. Two highlights of Castro's ongoing…
Meeting the Challenges of Modeling Astrophysical Thermonuclear Explosions: Castro, Maestro, and the AMReX Astrophysics Suite
M. Zingale, A. S. Almgren, M. G. Barrios Sazo +9
We describe the AMReX suite of astrophysics codes and their application to modeling problems in stellar astrophysics. Maestro is tuned to efficiently model subsonic convective flow…
Nyx: A Massively Parallel AMR Code for Computational Cosmology
Ann Almgren, John Bell, Mike Lijewski +2
We present a new N-body and gas dynamics code, called Nyx, for large-scale cosmological simulations. Nyx follows the temporal evolution of a system of discrete dark matter particle…
CASTRO: A New Compressible Astrophysical Solver. III. Multigroup Radiation Hydrodynamics
W. Zhang, L. Howell, A. Almgren +3
We present a formulation for multigroup radiation hydrodynamics that is correct to order using the comoving-frame approach and the flux-limited diffusion approximation. We…
