Combine Flux/Concentration BC in Electrochemical Species Model
 

I am using the electrochemical species model in StarCCM, and at a particular interface I would like to specify the following for the two electrochemical species in my system:

- Electrochemical Species A: Concentration = 1 kmol/m3.
- Electrochemical Species B: Flux = 0 kmol/m2.s.

Unfortunately, in the 'Wall Electrochemical Species Option' I can select only select 'impermeable', 'specify flux', or 'specify concentration' for all species. I do not know how to specify a concentration of one species (species A), and to specify a flux/specify impermeable for the other species (species B).

Is this possible in some way?
Thanks
