rohitsub is on a distinguished road

I am trying to model a non reacting opposing flow problem in fluent. I am expecting diffusion of species 1 in towards the inlet of species 2. But, that diffusion is not happening despite of turning on the inlet diffusion model.

Also, could someone tell me more about Differential Viscosity model in k-e RNG turbulence model? I am not getting any turbulence viscosity with that model.
