Dear all,

I am doing FRA. We have input 

PSD data in in all direction.

 

rms value in terms of g in  x y z direction.

how can we can get max displacement and max stress in output .

I am new  in dynamics.

If any deck will be available it will be more helpful for me.

Also tell me step by step .

Thanks and regards
