Hi All

I am trying to simulate mixing between 2 fluids (Fluid A &B) in microchannels. I am currently using the species model to study diffusion of these 2 fluids to study their interaction and how mixing is enhanced. For my preliminary model, I tried to specify the mixture constituents as waterA and waterB. However in my boundary condition window I only get 1 kind of fluid where the mass fraction can be specified. I would like to know if I am missing out on some other functions in the previous steps thereby disabling the 2nd fluid to show up in my boundary condition window.

I am new to the species model and have been trying to figure this out for the past few days to no avail.

Best Regards
Lakshmi
