Eigenfrequency

Find natural vibration frequencies and mode shapes.

Where to find it

System Solver workspace → Eigenfrequency

How to use it

Choose Eigenfrequency, then select the new or existing feature in Model Builder. Check supports and inertia, choose the requested mode count and search shift, then inspect each mode in Results.

Result

Successful runs provide solution data for plots, tables and evaluations in Results.

Troubleshooting

Mode-shape amplitude is relative, not a predicted displacement under a physical load.
