Hi to everyone

Could you please give me an advice to choose the right solver?

Case:
I have a domain which is filled with oxygen (< 200ppm) and nitrogen (>99.9%). Furthermore there is an outlet and an inlet.
Through the inlet pure nitrogen flows into the domain, at the outlet nitrogen flows out of the domain (with Reynoldsnumber lower than 50). But, and here comes the tricky part, oxygen flows from the environment into the domain (probably by diffusion) - at the end i would like to have a steady state solution (laminar).

I could simulate this with a scalarTransportFoam, but there wouldn't be any interaction between the different species and in a steady-state solution everything would be just nitrogen.

So which solver would you advice?

Thanks for every single answer!
