Quokka 25.01

Notable changes in this release include a code reorganization into subdirectories, hydro robustness updates in the presence of source terms, piecewise power-law opacity models for multigroup radiation, additional ISM physics in the radiation solver, support for unit systems (with metadata included in output files), and enforcement of a minimum version of the AMD ROCm toolkit (to avoid compiler bugs).

Known issues

• Self-gravitating particles may traverse more than one cell per timestep, which can cause crashes (see #833). This will be fixed in a future release of Quokka.

Quokka 21.10

Notes

This is the first release of Quokka! This version is well-tested on CPUs and NVIDIA GPUs and includes an automated test suite (see README.md) of 1D problems and additional problems (not yet automated) in 2D and 3D provided in the src subdirectory. For simplicity (and following AMReX and other codes), we have chosen to use "calendar versioning," denoting each release with the year and month.

What's Changed

• Refactor kernels to use AMReX abstractions by @BenWibking in #2
• added AMR using amrex::AmrCore by @BenWibking in #4
