Find natural vibration frequencies and mode shapes.
Find natural vibration frequencies and mode shapes.
Where to find it
System Solver workspace; Model Builder → System Solvers
How to use it
Check supports and inertia, choose the requested mode count and search shift, then inspect each mode in Results. Choose Run System Solver, then select the completed solution under Results.
Settings and initial values
| Setting | Initial value |
|---|---|
| Number of eigenvalues | 6 |
| Search shift | 0[Hz] |
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.
