Return coordinates of interface and velocity at that point?

Hi everyone!
I can't seem to find any examples of what I want to do.
I want to get the x-coordinate at given y-coordinates of the mass center of a free-falling liquid film and at that point get the velocity.

Is there anyway to do that with an UDF?

Cheers!

In my experience, what you are trying is quite complicated.

It easier if you compute the velocity average of the cells or faces in the liquid film.

Thanks for the answer, this was exactly what I was worried about

Does anybody know if this is doable in CFD-post?
