Hi How can I create a playable video file format in fluent6 ? thank you.

Hi..yes you can create mpeg video...2 options:

1) before start run (best for unsteady animation)

Define-animation (you can animate only countour or moving grid) after run completed Define playback write mpeg

2) run completed

display-scene panel and display-animate panel (you can animate pathlines,change view, light and other) see chapter 20 or user guide..there is sample inside
