MFIX-Exa: A path toward exascale CFD-DEM simulations

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