As an optional input the range and the number of frequencies which are taken into account for the optimisation can be modified with the Advanced User Settings.
Post Processing
The calculated first eigenfrequency over the iterations can be observed with a chart in the Post Processing. The frequency Event does not create any visible plots for the Failure Criterion or Stress on the geometry. But the influence of the frequency Event can be observed with the optimization achievement index which shows where material will be added (>0) to increase the first eigenfrequency of the part.
