ptorres is on a distinguished road
Hello to all!

I'm fairly new to CFD, having "really" started working on this about 2 weeks ago, so please bear that in mind before calling me names

I'm trying to develop a UDF to define mass transfer between two liquid phases, with 3 species, 2 that don't mix and 1 that does. so, defining the transfer between the interface, do I have to identify the cells that are in the interface, or fluent does that for me already? If I do have to identify them, how do I do that? I'm working with VOF model and species Transport.

Thank you!
