Standard results in modal frequencies

The results generated in a Modal Frequencies study enable you to determine the natural frequencies and mode shapes of your design. Online results are presented in the Browser.

When you first run a modal frequencies analysis, the Total Modal Displacement result for the first vibration mode is displayed by default.

Note: Modal displacement results are normalized. The legend shows no units, and you cannot change displacement units for this study type.

Total Modal Displacement (default) Total Modal Displacement, Modal Displacement X, Modal Displacement Y, Modal Displacement Z The normalized displacement for the selected vibration mode. Browser
Natural frequencies The natural frequency (Hz) for each calculated vibration mode. Mode dropdown above the legend
Mass participation factors The effective percentage of the total mass that moves in each global direction, for each mode. Results tab > Mass Participation panel > Mass Participation Factors
