Parameter

FRAPara command

Max number of mode

Amplitude Factor

Animation Frame

Including damping (Damped/
Undamped)

Logarithmic Step

FRAPARA/MAXMODE=10, AMP=1.0, CYCL=30, DAMP=TRUE, LOGSTEP=FALSE

 

•     FRAPARA: Parameter for Frequency Response analysis

•     MAXMODE: Max. no. of modes

•     AMP: Amplitude Factor

•     CYCL: Animation Frame

•     DAMP

•    “DAMP=FALSE” means undamped frequency response analysis without damping matrix.

•    “DAMP=TRUE” means damped frequency response analysis with damping matrix.

•     LOGSTEP

•    “LOGSTEP=FALSE” means frequency response analysis without Logarithmic Step.

•    “LOGSTEP =TRUE” means frequency response analysis with Logarithmic Step.

 

Note

This command is frequency response analysis option

You must define the FRAParameter command prior to the Frequency Response Analysis command
