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…
MAESTROeX: A Massively Parallel Low Mach Number Astrophysical Solver
Duoming Fan, Andrew Nonaka, Ann S. Almgren +2
We present MAESTROeX, a massively parallel solver for low Mach number astrophysical flows. The underlying low Mach number equation set allows for efficient, long-time integration f…
Improved Coupling of Hydrodynamics and Nuclear Reactions via Spectral Deferred Corrections
M. Zingale, M. P. Katz, J. B. Bell +3
Simulations in stellar astrophysics involve the coupling of hydrodynamics and nuclear reactions under a wide variety of conditions, from simmering convective flows to explosive nuc…
Toward Resolved Simulations of Burning Fronts in Thermonuclear X-ray Bursts
M. Zingale, K. Eiden, Y. Cavecchi +9
We discuss the challenges of modeling X-ray bursts in multi-dimensions, review the different calculations done to date, and discuss our new set of ongoing simulations. We also desc…
