Class
    Foam::maxDeltaxyz

Description
    Delta calculated by taking the maximum distance between the cell centre
    and any face centre.  For a regular hex cell, the computed delta will
    equate to half of the cell width; accordingly, the deltaCoeff model
    coefficient should be set to 2 for this case.
