The ShirgaonkarIB model calculates the drag force (viscous and pressure force) acting on each particle in a resolved manner (see Shirgaonkar et al. (2009): "A new mathematical formulation and fast algorithm for fully resolved simulation of self-propulsion", Journal of Comp. Physics). This model is only suited for resolved CFD-DEM simulations where the particle is represented by immersed boundary method.
