Does Fluent Calculate VOF before Momentum ?

Hello Guys,
I am writing a UDF involving VOF. I want to calculate the VOF values using the UDF instead of the Fluent formulation. These values will then effect the momentum and continuity equations. My question is , while using a UDF with a Segregated solver, what gets calculated first? Is it the UDF functions or is it the Continuity, Momentum equations?

I am writing a UDF for the following paper :
"A Numerical Study of Combined Heat and Mass Transfer in an Inclined
Channel Using the VOF Multiphase Model
R. Banerjee - Mark IV Automotive, Enterprise Drive, Rochester Hills, Michigan, USA"

If anyone has a UDF or something similar to this, please share it with me

yes, in your case, Fluent calculates Continuity, Momentum equations first.
And i am also wriing UDF for your paper described as above.
so will you contact me? my email is mengyue1@126.com...
