The Swell factors step is used to calculate loose volume from bank volume, for the purposes of dump capacity calculations.
This step allows users to set Swell Factors by Parcel Type.
By default, swell factors are applied to the <All Items> Mutex Subset. You can change it to “SimpleOreType“, “Haulage” or “Product“ from the Mutex Subset field dropdown (Mutex Subsets available are configured in the Parcel Subsets step).
