Thank u very much!

So if I want to call the area density of the phase interface in the UDF of the Euler two-fluid framework, is there any other way?
Because I try to use this macro, but the interface area returned is a fixed constant, probably around 0.006, I don't know what is the reason? I can't determine what level of thread is used by the second macro, just in the multiphase flow system of the Eulerian model, and what is the input of the parameter i? 

Anyway, I really need a way to get the key information of the interface area density of the phase interface.

I sincerely hope to get your help, thank you very much!
