Practical Effects of Integrating Temperature with Strang Split Reactions
M. Zingale, M. P. Katz, D. E. Willcox +1
For astrophysical reacting flows, operator splitting is commonly used to couple hydrodynamics and reactions. Each process operates independent of one another, but by staggering the…
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…
Dynamics of Laterally Propagating Flames in X-ray Bursts. I. Burning Front Structure
Kiran Eiden, Michael Zingale, Alice Harpole +3
We investigate the structure of laterally-propagating flames through the highly-stratified burning layer in an X-ray burst. Two-dimensional hydrodynamics simulations of flame propa…
Modelling low Mach number stellar hydrodynamics with MAESTROeX
A. Harpole, D. Fan, M. P. Katz +3
Modelling long-time convective flows in the interiors of stars is extremely challenging using conventional compressible hydrodynamics codes due to the acoustic timestep limitation.…
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…
