Phase velocity in VOF model UDF
 

Hi everybody,

Iam working on drop impact on a solid surface. What I want is to track the contact line velocity from the 2nd phase only during the spreading on the surface.
But I don't understand which variables I need to use to write my UDF.

I know that I have an access to the velocity magnitude for the mixture model but I only need the 2nd phase. Maybe I can substract the first phase velocity from the mixture phase ?

If someone can help me I would really appreciate.
Thanks for help,


Guillaume

Did you got an answer for that?

hello every body.
did u get the answer??
i am simulating a bubble column by vof and need the bubble velosity and diameter..but not know what to do!
