Class
    Foam::specieTransferMassFractionFvPatchScalarField

Description
    Abstract base class for specie-transferring mass fraction boundary
    conditions.

    Derived classes compute the actual species flux. Those fluxes are summed up
    by the specieTransferVelocityFvPatchVectorField velocity condition to
    generate the net mass transfer into or out of the patch. This mass-fraction
    condition then generates a corrective diffusive flux to ensure that the
    correct amounts of the transferring species are transported through the
    patch.
