Is there a way to access a point iso-surface in UDF and find its co-ordinate. I need to calculate velocity based on the movement of this point over time
Sir, I measure the velocity of a moving particle either bubble or droplet using image J software. However, there must be a way to measure velocity in fluent for multiphase flows.
Dear Rajeev Kumar Singh,
could you provide more information? Do you need only one particular point of the iso-surface?

Dear Rajeev,
I would suggest doing the post-processing either in CFD-Post or Tecplot. Both this post-processing package allows you to calculate velocity based on the movement of this point over time easily. Fluent is mainly a solver with limited post-processing capabilities.

Yes, basically this point is an iso-surface created out of two parameters (vof-fraction surface crossing touching a wall). Like the case of meniscus touching the wall of a tube. In 2D it will be appearing as a point. I have created a surface monitor and am able to track the velocity of this point. Now I want to use it in Fluent UDF to write a code for Dynamic Contact Angle based on the velocity of this point as reported in the surface monitor.
Hope this clarifies
Rajeev
