AMReX

Minimal walkthrough — the same shallow-water model as the NumPy tutorial, taken to generated C++ instead of a NumPy solve.

You need the AMReX container to compile and run. The codegen itself runs anywhere zoomy_core is installed:

apptainer pull zoomy_amrex.sif oras://ghcr.io/zoomylab/zoomy_amrex_sif:latest
apptainer run --bind $PWD:/workspace zoomy_amrex.sif jupyter

See Installation for every container and the three run modes (solver API, Jupyter, shell).

The maintained end-to-end cases are the AMReX test suite, library/zoomy_amrex/tests/ — wet and dry dam breaks, 2-D, a lake-at-rest well-balancing check, NumPy parity, and a two-rank parallel run.
