Natural Vibrations
Calculates the natural vibrations of the given model.
Inputs
| Name | ID | Description | Type |
|---|---|---|---|
| Model | Model | Model for which to calculate natural vibrations | Model |
| From index | FromInd | Index of first natural vibration mode to be calculated. Numbering starts from one. | Integer |
| Number of modes | NModes | Number of modes to be calculated | Integer |
| Maximum number of iterations | MaxIter | Maximum number of Mises vector iterations for determining the eigenvalues. | Integer |
| Epsilon | Eps | Convergence criteria for calculating the natural vibration frequencies. | Number |
Outputs
| Name | ID | Description | Type |
|---|---|---|---|
| Model with vibration modes as load-case results | Model | Model with vibration-modes stored as load-cases. Vibration modes are scaled such that the largest displacement is 1[m]. | Model |
| Natural frequencies [Hz] | NFrequ | Frequencies of the corresponding natural vibration mode | Number |
| Modal mass [kg] | MMass | Modal mass [kg] of the corresponding natural vibration mode | Number |
| Participation-factor in global x-, y- and z-direction | PartiF | Participation-factor in global x-, y- and z-direction. They are scaled according to the largest modal displacement being 1[m]. | Number |
