The Exascale Computing Project (ECP) is a U.S. Department of Energy’s Office of Science and National Nuclear Security Administration with the goal of ensuring that the U.S. has a capable exascale ecosystem in 2021. Here, we describe progress on one of the software projects funded by this program. Specifically, the CFD-DEM capability of the open-source MFiX code, developed by NETL, is being rebuilt as a separate, stand-alone code. The goal of this project is to simulate a 50kW chemical looping reactor with about 1 billion particles in 1 day of simulation time. The framework of this new code will be described as well as preliminary results toward the goal.
