How to define isotropic or anisotropic conditions?

I was wondering if anyone could shed some light on a doubt that I have.
I'm using the Mixture Model with K-Epsilon turbulence model to simulate a liquid-solid pipe flow.
The first case is homogeneous, latter I'll use heterogeneous conditions.
But for the homogeneous case first:
- I know that using a Wall Function, the anisotropic conditions are covered at the near-wall flow.
- However (and this is probably a very simple question) I can't figure out how to define isotropic or anisotropic
conditions to the rest of the domain (how to say to comsol that I want isotropic diffusion).
- The stabilizations tab shows an "isotropic diffusion" but I am not certain that is the same thing...
Hope I was clear and someone can help.
Cheers!
