  Hello
  What is the best method for VOF?
  I simulate drop impact to flow and i just want to refine drop not other interface.

  VOF is a method, ie it's one of the multiphase models. When you say drop impact, are you looking at droplets splashing, or do they form a film? With multiphase modelling (all models to slightly lesser extent) you need to understand what is going to happen before switching the software on as the physics influences the mesh too.

  For splashing you'll probably want VOF but given the mesh resolution you may also want to look at VOF to DPM.
