CFD-Post animation trouble

  I use CFD-Post to post-process Fluent results with a single *.cas file and multiple *.cdat files. All files are loaded into CFD-Post, and the complete history is successfully loaded. However, when I run the animation, the images do not change, both in the preview and in the output *.avi file. At the same time, when I switch frames manually using the slider, they change correctly. How can I fix this problem?

  Hi Gennadii,
  Can you try the same using Keyframe. Keyframe is more versatile than Timestep animation. Choose the the first timestep and create a keyframe, choose the next timestep and create the next keyframe. Specify the number of frames betwwen the keyframe.

    Hi CFD_Friend,
    Yes, your approach works, but for an animation with 100 timesteps, I would need to add 100 keyframes manually, which could take hours. Is there a way to automate this process? I mean, is it possible to automatically add all timesteps to the keyframe list?
