MagneX: A High-Performance, GPU-Enabled, Data-Driven Micromagnetics Solver for Spintronics
Andy Nonaka, Yingheng Tang, Julian C. LePelch +7
In order to comprehensively investigate the multiphysics coupling in spintronic devices, it is essential to parallelize and utilize GPU-acceleration to address the spatial and temp…
A New Re-redistribution Scheme for Weighted State Redistribution with Adaptive Mesh Refinement
Isabel Barrio Sanchez, Ann S. Almgren, John B. Bell +2
State redistribution (SRD) is a recently developed technique for stabilizing cut cells that result from finite-volume embedded boundary methods. SRD has been successfully applied t…
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…
CASTRO: A New Compressible Astrophysical Solver. II. Gray Radiation Hydrodynamics
W. Zhang, L. Howell, A. Almgren +2
We describe the development of a flux-limited gray radiation solver for the compressible astrophysics code, CASTRO. CASTRO uses an Eulerian grid with block-structured adaptive mesh…
