Eigenfrequency Gif or Avi and breathing modes

I have made a simple model of a 3d-square membrane and used solid mechanics and eigenfrequency analysis to get the eigenfrequencies. Now that i have them i am trying to make a gif or avi of the behavior of the membrane at those frequencies. AKA I want to take the fundamental mode with one peak in the center and create a video of that peak appearing on one side then disappearing and appearing again on the other side. I have seen this animation produced from 3.5a comsol but i can't find how to do it.

Doing the Eigenfrequency analysis and finding the first 30 modes yielded close to expected results for the modes that are out of plane. However, i can't seem to get it to produce the eigenfrequencies that produce in-plane modes, or breathing modes. Is there an option in the eigenfrequency analysis to specify what direction to look in for the peaks? AKA look in the XY plane instead of the Z direction for maximas in deformation.
