Hello 

I am trying to do frequency response analysis on my model. But i have no idea how to go ahead with the same. Can someone help me with this?

I wish to have frequency vs normalized response (normalized displacement ) plot/graph. Ex shown in following fig.

 

Thanks in advance.

    How can I have response in term of normalized displacement? Is there any output card for that??

    You need to output Displacement for node(s) of interest in the form of PHASE through control cards.
