Hi,

I am considering using Ansys Polyflow to simulate intermittent and continuous slot die coating of a moving substrate where the coating fluid is a viscoelastic liquid described with a differential viscoelastic model:

1. Does anyone know if Polyflow can simulate pinch-off of a liquid thread (i.e. the break-up of a continuum)?

2. Polyflow has the options of modelling interfacial/free-surface problems with the Volume-of-fluid (VOF) technique (Eulerian) or by tracking a deforming interface/free-surface (Lagrangian). For simulating a coating problem, is one technique better than the other? Is one technique preferable over the other for modelling the break-up of a liquid continuum?

Thank you.

Juan
