Magnetising the quokka code with fast, second-order accurate, error-correcting schemes for magnetohydrodynamics on GPUs
Neco Kriel, Elizabeth Cole-Kodikara, Benjamin Wibking +4
We implement a second-order accurate constrained transport (CT) magnetohydrodynamics (MHD) module with first-order flux correction in the open-source, adaptive mesh refinement (AMR…
AMReX-Astrophysics Microphysics: A set of microphysics routines for astrophysical simulation codes based on the AMReX library
Astro Microphysics Team, Khanak Bhargava, Abigail Bishop +15
The AMReX-Astrophysics Microphysics library provides a common set of microphysics routines (reaction networks and associated physics, equations of state, and various transport coef…
A novel algorithm for GPU-accelerated particle-mesh interactions implemented in the QUOKKA code
Chong-Chong He, Benjamin D. Wibking, Aditi Vijayan +2
We present a novel, GPU-optimized algorithm for particle-mesh interactions in grid-based hydrodynamics simulations, designed for massively parallel architectures. This approach ove…
An Asymptotically-Correct Implicit-Explicit Time Integration Scheme for Finite Volume Radiation-Hydrodynamics
Chong-Chong He, Benjamin D. Wibking, Mark R. Krumholz
Numerical radiation-hydrodynamics (RHD) for non-relativistic flows is a challenging problem because it encompasses processes acting over a very broad range of timescales, and where…
A radiation hydrodynamics scheme on adaptive meshes using the Variable Eddington Tensor (VET) closure
Shyam H. Menon, Christoph Federrath, Mark R. Krumholz +3
We present a new algorithm to solve the equations of radiation hydrodynamics (RHD) in a frequency-integrated, two-moment formulation. Novel features of the algorithm include i) the…
VETTAM: A scheme for radiation hydrodynamics with adaptive mesh refinement using the variable Eddington tensor method
Shyam H. Menon, Christoph Federrath, Mark R. Krumholz +3
We present Variable Eddington Tensor-closed Transport on Adaptive Meshes (\texttt{VETTAM}), a new algorithm to solve the equations of radiation hydrodynamics (RHD) with support for…
Quokka: A code for two-moment AMR radiation hydrodynamics on GPUs
Benjamin D. Wibking, Mark R. Krumholz
We present Quokka, a new subcycling-in-time, block-structured adaptive mesh refinement (AMR) radiation hydrodynamics code optimised for graphics processing units (GPUs). Quokka sol…
