PARAM, GYROAVG

Bulk Data Entry Used to select the frequency response analysis formulation type for rotor dynamics analysis.


Parameter	Values	Description
`GYROAVG`	<0, -1>	0 (Default) The frequency-dependent rotor dynamics terms are calculated for each frequency. A frequency-dependent looping option is activated, however, the run time is higher compared to PARAM, `GYROAVG`, -1 as the calculation process has to be repeated for each frequency in the specified range. -1 The frequency-dependent looping does not occur and an average frequency method is used to calculate the rotor dynamic terms. The run time is lower compared to PARAM, `GYROAVG`, 0 as this option avoids intensive calculations for each frequency. PARAM, WR3 and PARAM, WR4 must be specified for this formulation to include rotor damping. Alternatively, `WR3` and `WR4` may be specified for each rotor in its corresponding RSPINR card. Refer to Rotor Dynamics in the User Guide for more details.
