I am trying to create a simulation that would simulate a mixture tank of two different liquids along with Air. Imagine a paint mixing tank. At the top we would have air. In the bottom we would have a liquid (water is fine for now). I am using a multi-phase simulation Where I have setup air and water as my two phases. For the Water domain I would like to use water that is white and water that is red. Mixing the two together would give me pink water. I have setup 3 materials Air, Water White and Water Red. The initial condition would be Air in the top domain and 100% Water White in the bottom domain. At the inlet I would like to bring Water Red into the Water White Domain. In the end I would plot the volume fraction of Water Red or Water White. Is there a way to introduce 2 different liquids in a domain and include the air domain?
Here is my current setup.
