Reply To: How to improve the convergence of the EWF model?

[Rob]

I need to tread carefully as I'm unable to use "detailed engineering knowledge" on the Forum. I've done a fair bit of work with EWF with partners. 

First pointer is to fully understand the condensation rates and likely film flow regime. Make sure the facet growth rate is low, and avoid splits in the surface if you have poly mesh: note my comment on cell size. From there you may find transient film with steady flow to be appropriate, read the solver theory to see how energy is handled for phase change.
