Default Species Sink Term - Porous Media

Please help!

I am writing a UDF species sink term (Kg/m3 s) in a porous zone. The question is, since Fluent accounts for porous media as a momentum sink, how can I, in the UDF, apply my sink term to work only within the volume of voids in the porous zone, not the total volume?

Another question, how can I calculate the mass fraction of species only in the volume of voids?
