Class
    Foam::InjectionModel
 
Description
    Templated injection model class.
 
    The injection model nominally describes the parcel:
    - position
    - diameter
    - velocity
    In this case, the fullyDescribed() flag should be set to 0 (false). When
    the parcel is then added to the cloud, the remaining properties are
    populated using values supplied in the constant properties.
 
    If, however, all of a parcel's properties are described in the model, the
    fullyDescribed() flag should be set to 1 (true).
