Class
    Foam::fvPatchField
 
Description
    Abstract base class with a fat-interface to all derived classes
    covering all possible ways in which they might be used.
 
    The first level of derivation is to basic patchFields which cover
    zero-gradient, fixed-gradient, fixed-value and mixed conditions.
 
    The next level of derivation covers all the specialised types with
    specific evaluation procedures, particularly with respect to specific
    fields.
