Hello everyone,

I've a question about how to define the diffusion
coefficient of a certain material in CFX please?
Because I want to simulate the diffusion between two
liquids in a domain. I haven't found any option that
we can plug into the value of diffusion coefficient
when we establish a material.

Thanks a lot in advance.
