MFIX-Exa is a computational fluid dynamics–discrete element model (CFD-DEM) code designed to run efficiently on current and next-generation supercomputing architectures. MFIX-Exa combines the CFD-DEM expertise embodied in the MFIX code—which was developed at NETL and is used widely in academia and industry—with the modern software framework, AMReX, developed at LBNL. The fundamental physics models follow those of the original MFIX, but the combination of new algorithmic approaches and a new software infrastructure will enable MFIX-Exa to leverage future exascale machines to optimize the modeling and design of multiphase chemical reactors.

MFIX-Exa是一种计算流体动力学离散元模型（CFD-DEM）代码，旨在在当前和下一代超级计算体系结构上高效运行。MFIX-Exa将MFIX代码中体现的CFD-DEM专业知识与NLNL开发的现代软件框架AMReX结合在一起，MFIX代码是NETL开发的，并在学术界和工业界得到了广泛使用。基本物理模型遵循原始MFIX的模型，但是新算法方法和新软件基础结构的结合将使MFIX-Exa能够利用未来的百亿亿级机器优化多相化学反应器的建模和设计。
