Adapting AREPO-RT for Exascale Computing: GPU Acceleration and Efficient Communication
Oliver Zier, Rahul Kannan, Aaron Smith +2
Radiative transfer (RT) is a crucial ingredient for self-consistent modelling of numerous astrophysical phenomena across cosmic history. However, on-the-fly integration into radiat…
Non-ideal magnetohydrodynamics on a moving mesh II: Hall effect
Oliver Zier, Alexander C. Mayer, Volker Springel
In this work we extend the non-ideal magnetohydrodynamics (MHD) solver in the moving mesh code AREPO to include the Hall effect. The core of our algorithm is based on an estimation…
Simulating cold shear flows on a moving mesh
Oliver Zier, Volker Springel
Rotationally supported, cold, gaseous disks are ubiquitous in astrophysics and appear in a diverse set of systems, such as protoplanetary disks, accretion disks around black holes,…
Simulating cosmic structure formation with the GADGET-4 code
Volker Springel, Rüdiger Pakmor, Oliver Zier +1
Numerical methods have become a powerful tool for research in astrophysics, but their utility depends critically on the availability of suitable simulation codes. This calls for co…
