Class
    Foam::PatchInjection

Group
    grpLagrangianIntermediateInjectionSubModels

Description
    Patch injection.

    User specifies:
      - Total mass to inject
      - Name of patch
      - Injection duration
      - Initial parcel velocity
      - Injection volume flow rate

    Properties:
      - Parcel diameters obtained by distribution model
      - Parcels injected randomly across the patch
