  Hi, i have done a modal analysis, and now i need to do a transient analysis(based on modal analysis) in which i apply some displacement steps, and i would have as output the vibration amplitude.
  
  thank you for your help.

  Check your settings - are they all sensible?

  i checked all settings. i supposed they are ok.
  
  to try i apply only a easy displacement of 40 mm in 0.2 sec, and i would find vibration amplitude.
