24 Class
25  Foam::gradingDescriptor
26 
27 Description
28  Handles the specification for grading within a section of a block
29 
30  blockFraction: the fraction of the block the section occupies
31 
32  nDivFraction: the fraction of the divisions of the block allocated to
33  the section
34 
35  expansionRatio: the expansions ratio for the grading with the section of
36  block defined as the ratio of the size of the division at either and
37  of the section.
