SediFoam is a hybrid CFD—​DEM solver for particle-laden flows based on two open-source codes: OpenFOAM, an object-oriented CFD platform by OpenCFD, and LAMMPS, a highly efficient molecular dynamics solver by Sandia National Laboratories. The algorithms used in this solver are published in Xiao and Sun [Xiao2011], Sun and Xiao [Sun2015a], [Sun2015b], and Gupta et al.[Gupta2015a]. The solver has ben rigorously and extensively validated [Gupta2015b]. A capability demonstration of the present solver in the context of sediment transport is published in Sun and Xiao [Sun2016]. Other application include sand dune migration [Sun2016b].
