Class
    Foam::ConeInjection

Group
    grpLagrangianIntermediateInjectionSubModels

Description
    Multi-point cone injection model.

    User specifies:
      - time of start of injection
      - list of injector positions and directions (along injection axes)
      - number of parcels to inject per injector
      - parcel velocities
      - inner and outer half-cone angles

    Properties:
      - Parcel diameters obtained by distribution model
