- Offline access
- Yeschecked 23 Sep 2026
- Parallel computing
- It uses MPI and OpenMP parallelization and is built on the AMReX adaptive mesh refinement library.checked 9 Oct 2026
- Performance
- The code uses MPI and tiled OpenMP parallelism and is described as scaling from 1 to 10,000s of cores.checked 8 Oct 2026
- Physics
- It supports arbitrary equations of state, general nuclear reaction networks, and implicit thermal diffusion.checked 9 Oct 2026
- Purpose
- MAESTROeX is an astrophysical hydrodynamics code for modeling low Mach number stratified flows, including convection in stars and atmospheres.checked 9 Oct 2026
- Regression checks
- A nightly regression test suite checks outputs bit-for-bit against stored benchmarks for many problem setups, including science runs.checked 9 Oct 2026
- Reproducibility
- Plotfiles record build and run environment details and source code versions to help recover the code base used for previous results.checked 9 Oct 2026
Where it runs
- Low Mach method
- It filters out sound waves while retaining relevant compressibility effects, allowing larger timesteps for low Mach number flows.checked 9 Oct 2026
