I have created a simple model, a plate surface. I fixed one side with zero for all 6 degrees of freedom and other sides are free. I want to make Modal analysis and I made it with results for the first three mode shapes. I got the frequencies by "read Results"
hi, you can do modal analysis and see natural frequency by read results such as a text file and can see shape mode of each natural frequency by results viewer that you can change number of natural frequency on it and see shape mode .
if you have a problem, send your problem (Dimension) and material properties and .... to help you better.
