Hello Joseph,


The model seems complicated. Here are a couple of things to try



  • Try to switch off the energy and radiation models and just solve the flow. Try to see if you are able to get good physical results for flow and VOF.

  • Attempt to build in the complexity layer by layer.

  • Try and use the explicit VOF formulation as opposed to implicit. 

  • Please make sure that your are satisfying the CFL stability criterion.

  • Calculate your dimensionless numbers and double-check to ensure your Fluent model is set-up to solve the correct physics.


It is always a good practice to start small and built on top of that. Simplify your problem and resolve things one at a time. This will help you isolate your error.


Hope this helps.


Best,


Karthik
