This tutorial shows how you can use the Generative Structural Analysis module from Catia V5 in order to see the natural vibration frequencies of a eolian propeller.
Step 1: Make the meshes
In order to make the meshes, just calculate the frequency case solution, as you can see in the video above.
Step 2: Von Mises stress
Add the Von Mises stress (nodal values).
