Class
    Foam::slicedFvPatchField
 
Group
    grpGenericBoundaryConditions
 
Description
    Specialization of fvPatchField which creates the underlying
    fvPatchField as a slice of the given complete field.
 
    The destructor is wrapped to avoid deallocation of the storage of the
    complete fields when this is destroyed.
 
    Should only used as a template argument for SlicedGeometricField.
