My harmonic analysis results changing when I begin to animate results, which is correct?

      Hello,

      I am currently running a harmonic analysis on a flexure to find out the linear motion in the horizontal direction. I have completed the analysis and my results set can be seen below. Although when I animate my results the results legend on the left hand side changes. Is there a way to stop this? Or is one of these results set 'correct' and the other arbitrary?

      When you plot the static image of results, you are getting the resuls at phase angle of 0 i.e. you are plotting the real part of the solution. When you do the animation (over time) that essentially has to keep changing the phase angle and what you are seeing is the maximum response at that frequency. If you want to find the max response at this frequency you can plot the amplitude.
