Class
    Foam::diameterModels::sizeGroup

Description
    This class represents a single sizeGroup belonging to a velocityGroup.
    The main property of a sizeGroup is its representative diameter. The
    corresponding volScalarField f<number>.<phaseName>.<populationBalanceName>
    gives the volume fraction of the sizeGroup such that all sizeGroup fractions
    over a velocityGroup must sum to unity. The field is either read from the
    startTime directory if present or constructed from a reference field called
    f.<phaseName>.<populationBalanceName> where the boundary condition types
    must be specified. All field and boundary condition values are reset to
    match the "value" given in the sizeGroup subdictionary.

Usage
    \table
        Property     | Description             | Required    | Default value
        d            | Representative diameter | yes         |
        value        | Field and BC value      | yes         |
    \endtable

    Example
    \verbatim
    f1
    {
        d            3e-3;
        value        1.0;
    }
    \endverbatim
