Hi everyone

I simulated air bubble in water 3D, I used VOF model, air velocity inlet, and pressure outlet, also other things.
i want to see trajectory of bubble, how I can do it?

I think that i have few options.

-Track particle, I have read about it, but I havent learnt enough to do it, if this is the right way to do it, can you help me?
-animate, my problem with this, is that I have a 3D model and I see volume of fraction, so the water not allow me see the bubble, maybe there is a way
to see only the air phase and contour.??
-I used pathline, but this only show the trajectory of a non-mass particle at current timestep (i have understanding), i want to see trajectory of a bubble in a period of time (since formation until bubble arrive at free surface)

someone can help me??
maybe exist another way?

best regards
