<p style="margin-left:.5in"><span style="font-family:Calibri;color:black">My question would be about the best practice to animate mode shapes in paraview. I have an initial shape of points (x,y,z coordinates) subjected to different frequencies. There are 493
DoFs and 19 modes. What would be the best way to animate it in paraview and which input file should be used? Thank you!<o:p></o:p></span></p>
