However, the rheology of a general suspension is strongly affected by the particle shape. Consequently, taking into account the complete particle geometry is required for first-principles-based suspension modeling. In this work, we present further developments in a purely OpenFOAM-based CFD-DEM solver (openHFDIB-DEM) that allows for fully-resolved, four-way coupled simulations with arbitrarily-shaped solids. The solid bodies are included in the computational domain via a hybrid fictitious domain-immersed boundary (HFDIB) method built based on previous works Municchi and Radl. The movement of individual solids inside the computational domain is described via a custom variant of soft DEM, i.e. allowing slight overlaps between different particles. The solver codes, including several tutorials, may be retrieved from https://github.com/MartinKotoucSourek/openHFDIB-DEM.
