MFIX-Exa is a CFD-DEM code designed to run efficiently on current and next-generation supercomputing architectures, leveraging the expertise of MFIX and the software framework AMReX to optimize modeling and design of multiphase chemical reactors on future exascale machines.
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.
