Welcome to the home of MFC!
MFC simulates compressible multi-component and multi-phase flows, [amongst other things](#what-else-can-this-thing-do).
MFC is written in Fortran and uses metaprogramming to keep the code short (about 20K lines).
**Welcome!**
MFC simulates compressible multi-phase flows, [among other things](#what-else-can-this-thing-do).
It uses metaprogramming to stay short and portable (~20K lines).
MFC conducted the largest known, open CFD simulation at <a href="https://arxiv.org/abs/2505.07392" target="_blank">101 trillion grid points</a> (as of July 2025).

MFC is used on the latest leadership-class supercomputers.
It scales <b>ideally to exascale</b>; [tens of thousands of GPUs on NVIDIA- and AMD-GPU machines](#is-this-really-exascale) on Oak Ridge Summit and Frontier.
It scales <b>ideally to exascale</b>; [tens of thousands of GPUs on NVIDIA- and AMD-GPU machines](#is-this-really-exascale) on Oak Ridge Frontier, LLNL El Capitan, CSCS Alps, among others.
MFC is a SPEChpc benchmark candidate, part of the JSC JUPITER Early Access Program, and used OLCF Frontier and LLNL El Capitan early access systems.
