I'm trying to model an evaporating interface. I have a 1D model with two domains, one water and one air. I want to model the evaporation of the water into the air and track the interface as material leaves it. I am currently using Transport of Diluted Species, Heat Transfer in Fluids, and the Moving Mesh Physics in my model.
I have been advised to use the mass flux from the Transport of Diluted species to drive the interface. Couple of problems I am having: 1. I don't see a variable for the mass flux in the equations view. I thought this was a built in variable for these physics options. Any ideas how I can access the mass flux to then use in a later physics step? 2. Moving Mesh. Both domains are selected for the transport of diluted species and heat transfer in fluids, When I get to Moving Mesh>Fixed Mesh it is already selected as both domains (I don't want this to be fixed) and I can't select the domains to set them to Prescribed Mesh Displacement. Any ideas on what is going on? Thanks,
