TR.37.6.2 Define Harmonic Output Frequencies
If Harmonic is requested above, then optionally include the next input.
FREQUENCY (FLO f1 FHI f2 NPTS f3 ( MODAL ) FLIST freqs )
Where:
| Parameter | Description |
|---|---|
| FLO f1 | Lowest frequency to be included in Harmonic output. Default to half the first natural frequency. |
| FHI f2 | Highest frequency to be included in Harmonic output. Default to highest frequency plus largest difference between two consecutive natural frequencies. |
| NPTS f3 | Number of plot frequencies to be included between natural frequencies. Defaults to 5 (7 if fewer than 10 modes) (3 if more than 50 modes). These points are added to improve the graphic display of responses versus frequency.
The natural and forcing frequencies are automatically included in the plot frequencies. |
| MODAL | This option causes the natural frequencies between FLO and FHI to be added to the list of forcing frequencies. |
| FLIST freqs | List of forcing frequencies to be included in the Harmonic analysis. Continue freqs input to additional lines by ending each line except the last with a hyphen.
Only forcing frequencies will be used to create load case results and print results. |
