Class
    Foam::CellZoneInjection

Group
    grpLagrangianIntermediateInjectionSubModels

Description
    Injection positions specified by a particle number density within a cell
    set.

    User specifies:
      - Number density of particles in cell set (effective)
      - Total mass to inject
      - Initial parcel velocity

    Properties:
      - Parcel diameters obtained by PDF model
      - All parcels introduced at SOI
