A parallel dual-grid multiscale approach to CFD–DEM couplings [PDF]
Journal of Computational Physics, 2019 In this work, a new parallel dual-grid multiscale approach for CFD-DEM couplings is investigated. Dual- grid multiscale CFD-DEM couplings have been recently developed and successfully adopted in different applications still, an efficient parallelization for such a numerical method represents an open issue. Despite its ability to provide grid convergent
