In this presentation, we will introduce OpenHFDIB-DEM, an open-source tool that integrates computational fluid dynamics (CFD) with the hybrid fictitious domain immersed boundary (HFDIB) approach and the discrete element method (DEM). OpenHFDIB-DEM is developed as a monolithic extension to the OpenFOAM library including our custom DEM implementation. Presently, it allows for CFD-DEM simulations of flows laden with up to ten thousand arbitrarily shaped solids defined as triangulated surfaces, operates at roughly 70 % of parallelization efficiency, and, for spheres, it provides results consistent with LIGGGHTS.
