Hi!

I tried to make a modal analisys of a model composed by many components and different materials. The result shows only one component moving and the others no, it seems that each component is not in contact with the others. What's the error that i made?

Grazie

    Check your assembly conditions!

    You should define something to assembly your components unless you will see some rigid modes in results.

    As @Q.Nguyen-Dai posted check the assembly connectivity. 

     

    If you have used contacts (stick, slide) change to Freeze or tie contacts and try again.
