Caedium only, no other software.

To replicate, take a converged CFD simulation:

1. Click the Freeze button
2. Click Beginning
3. Create a rectangle
4. Transform the rectangle to start point of the animation
5. Click End
6. Transform the rectangle to the end point of the animation
7. Click Beginning and click Play to check the animation
8. Click Beginning
9. Drag and drop the Result you want to visualizing onto the rectangle
10. Click Record to record the animation
11. Click Play to see the complete animation
12. Toggle Record to complete the animation recording

Clicking Loop will continuously loop the animation.

Confession: I did use GIMP to convert the avi file into a gif file.
