harmonic response

    • Samuele Luigetti

      Hello everybody, referring to the frequency response related to the deformation of a structure in the harmonic analysis, if i set the geometry on all bodies, the amplitude reported on the plot at which point of the strucuture are referred?

      I don't know the answer to your question but I would guess that when all bodies are selected, the deformation is plotted at whatever location has the maximum deformation at each frequency.  I don't find such a plot very useful.

      I always select a vertex to plot the directional or total deformation versus frequency in a Harmonic Response analysis so I know exactly where the amplitude is being reported.

      From that FRF plot, I note the frequency of the peak response and request a Stress plot at that frequency so I can see where on the structure the peak stress can be found.
