MMPIC
The MMPIC solids model tracks the position and trajectory of computational parcels, statistical groups of particles that share the same physical characteristics (e.g. diameter and density). In the present formulation, different diameter particles of the same material must be defined as separate solid phases, each with its own statistical classification. Figure 1 illustrates this idea.
Figure 1: Visual concept of particle consolidation to computational parcels by type. (a) A single cell populated with particles. (b) The same single cell after a statistical weight has been applied to each particle type.
If one imagines that Figure 1 represents a single cell, there are 15 blue particles represented by 3 blue computational parcels, and 12 green particles represented by 3 green computational parcels. In simple terms, 1 blue parcel carries a statistical weight of 5 particles/parcel, and 1 green parcel carries a statistical weight of 4 particles/parcel.
