hi I'm simulating a DPM model

I found a variable about wall film called wall coverage

In the User's Guide, it says "Wall Coverage(in the Wall Film… category) is the fraction of the wall surface covered by the wall film."

However, I can't find the criterion of the wall coverage whether the wall surface is covered by the film

I would like to know how the program determines if the surface is wet

With DPM the film comprises many droplets so coverage calculations aren't trivial. The Eulerian Wall Film is a facet (surface) model so behaves differently.

In Eulerian Wall Film, User's Guide and Theory Guide says "Film Coverage" variable is considered by critical film height with 1e-10 m.

I was wondering similar process is applied to "Wall Coverage" variable in Lagrangian Wall Film.
