> **2025 Gordon Bell Prize Finalist** - MFC simulates compressible multi-phase flows at exascale, using [Fypp](https://fypp.readthedocs.io/en/stable/fypp.html) metaprogramming in ~40K lines of Fortran. It conducted the [largest known public CFD simulation](https://arxiv.org/abs/2505.07392) at **200 trillion grid points** and 1 quadrillion degrees of freedom, scaling ideally to >43K AMD APUs on [El Capitan](https://hpc.llnl.gov/hardware/compute-platforms/el-capitan) and >33K AMD GPUs on [Frontier](https://www.olcf.ornl.gov/frontier/).

## Why MFC?
- **Performant at exascale** - Ideal weak scaling to 43K+ GPUs. Near compute-roofline behavior. [Compile-time case optimization](https://mflowcode.github.io/documentation/running.html) for ~10x speedup.
- **Compact code** - ~40K lines of Fortran with [Fypp](https://fypp.readthedocs.io/en/stable/fypp.html) metaprogramming. Small enough to read and modify; powerful enough for [Gordon Bell](https://awards.acm.org/bell).
- **Native multi-phase** - 4, 5, and 6-equation models, phase change, surface tension, bubble dynamics, and Euler-Lagrange particle tracking, all built in.
- **Portable** - NVIDIA and AMD GPUs, CPUs, laptops to exascale. Docker, Codespaces, Homebrew, and [16+ HPC system templates](https://mflowcode.github.io/documentation/running.html).
- **Tested** - 600+ regression tests per PR with line-level [coverage](https://app.codecov.io/gh/MFlowCode/MFC) on GNU, Intel, Cray, NVIDIA, and AMD compilers.
- **Easy to shape** - If MFC is missing something you need, do notExcerpt of 15,947 characters
