24 Class
25  Foam::diameterModels::sizeGroup
26 
27 Description
28  This class represents a single sizeGroup belonging to a velocityGroup.
29  The main property of a sizeGroup is its representative volume. The
30  corresponding volScalarField f'number'.'phaseName'.'populationBalanceName'
31  gives the volume fraction of the sizeGroup such that all sizeGroup fractions
32  over a velocityGroup must sum to unity. The field is either read from the
33  startTime directory if present or constructed from a reference field called
34  f.'phaseName'.'populationBalanceName' where the boundary condition types
35  must be specified. All field and boundary condition values are reset to
36  match the 'value' given in the sizeGroup subdictionary.
37 
38  The corresponding physical diameter that is representative for the class is
39  computed by a separate shapeModel, specified in the velocityGroupCoeffs
40  dictionary.
