Hi, I'm modelling moisture diffusion into this Bi-material,
To achieve this I enable "Species Transport" to enable mixture to define H2O Mass Fraction & Diffusivity.
In my Case, I am trying to make moisture (Mixture) diffuse into 2 material. Hence I would require to set different Mass Diffusivity & Porosity in this two material.
I've created two "Mixture" to treat on different material, however there is only One Mixture available from the drop down selection.
Therefore I wasn't able to set Mass Diffusivity on the another material.
How do I resolve this?
I wonder should I be using VOF, Mixture, Eulerian Instead? But the problem is I'm only have one fluid (Moisture) in this case.
