I want to make the DPM particle tracks pulse mode into a video file to play in the presentation, but I don't know how to get it?! Some one has suggested to use a camcorder to record it, Is there other better ways? Thanks a lot!

I think u can define an animation sequence before iterating it. For this u have to go to Solve--> Animate --> Define. Hope it helps

Thank you very much! I will have a try.

Use a video screen capture program like "Hypercam". Fluent is quite weak in using scene/animations for particles.
