Animation Playback not representing Fully Reversing Loads for Fatigue

    • Sara Duello

      I set up a fatigue analysis with fully reversed loading and viewed the animation playback to see the loads reverse. However, the only case that the animation playback shows is the model going from 0 loading to all loads applied. This does not represent the case I am trying to simulate, and it doesn't make sense to me why what would be the case. I have been unable to find any other forum topic or resources about fixing this problem or even addressing why the animation playback is inaccurate.

      I have included a link to a video that demonstrates my same issue. The timestamp is where the animation is played, but the previous parts show the process this user followed to set up the simulation.

      Hello Sara,

      I don't know details about how the developers choose to implement any specific feature in the software, but I expect that making the animation show fully reveresed motion for a fully reversed load instead of animation that shows a zero-based load was just not a high enough priority for the developers. If enough users compliain, it may be put in the list of improvements for a future version.  What most users care about is that the calculation of fatigue life was done correctly for both zero-based loading and fully reversed loading.
