Class
    Foam::extrapolatedCalculatedFvPatchField

Description
    This boundary condition applies a zero-gradient condition from the patch
    internal field onto the patch faces when \c evaluated but may also be
    assigned.  \c snGrad returns the patch gradient evaluated from the current
    internal and patch field values rather than returning zero.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            extrapolatedCalculated;
    }
    \endverbatim
