Mixture vs VOF
 
I am simulate a 3D-3phase model (water, air and sand). When I use VOF for water-air only Water and Air are immiscible and I can get a nice surface of water. However, when I use the mixture model for water-sand-air, I want to have mixture between water and sand, but not between water and air. In results that I've got water and air mix.

How can I select the option in Mixture model to have water-air immiscible and water-sand miscible?

I will appreciate your help.

Sincerely,

Humberto
