Fast, Stable, and Physical: Hyperbolic, Magnetic Field-Aligned Diffusion in SPH
Nicholas Owens, James Wadsley, Robert Wissing +1
In this paper, we introduce the first implementation of magnetic field-aligned hyperbolic diffusion for standard smoothed particle (magneto-)hydrodynamics (SPH), and its linear-exa…
EuroHPC SPACE CoE: Redesigning Scalable Parallel Astrophysical Codes for Exascale
Nitin Shukla, Alessandro Romeo, Caterina Caravita +36
High Performance Computing (HPC) based simulations are crucial in Astrophysics and Cosmology (A&C), helping scientists investigate and understand complex astrophysical phenomena. T…
In-Situ High Performance Visualization for Astronomy & Cosmology
Nicola Tuccari, Eva Sciacca, Yolanda Becerra +4
The Astronomy & Cosmology (A&C) community is presently witnessing an unprecedented growth in the quality and quantity of data coming from simulations and observations. Writing resu…
Optimized smoothing kernels for SPH
Robert Wissing, Thomas R. Quinn, Ben Keller +2
We present a set of new smoothing kernels for smoothed particle hydrodynamics (SPH) that improve the convergence of the method without any additional computational cost. These kern…
Axisymmetric smoothed particle magneto-hydrodynamics
Domingo García-Senz, Robert Wissing, Rubén M. Cabezón +2
Many astrophysical and terrestrial scenarios involving magnetic fields can be approached in axial geometry. Although the smoothed particle hydrodynamics (SPH) technique has been su…
Axisymmetric magneto-hydrodynamics with SPH
Domingo García-Senz, Robert Wissing, Rubén M. Cabezón
Many interesting terrestrial and astrophysical scenarios involving magnetic fields can be approached in axial geometry. Even though the Lagrangian smoothed particle hydrodynamics (…
Smoothed particle magnetohydrodynamics with the geometric density average force expression
Robert Wissing, Sijing Shen
We present a novel method of magnetohydrodynamics (MHD) within the smoothed particle hydrodynamics scheme using the Geometric Density average force expression (GDSPH). GDSPH has re…
