      The parcel size is important for DEM and DDPM. In DEM simulations parcel size is used for the collision calculations. However in both cases we have to ensure that the volume of the parcel is smaller than the cell volume to ensure an accurate and stable solution. Please see attachment for details on calculating the parcel size Key word: DEM, DDPM, parcel size, time step size, parcel mass
