Figure 5.19 Eigenvalue Analysis dialog box [Parameter]

  • Frame per Cycle: Defines the value to animate a mode shape.

  • Start Time and End Time: Show the starting and ending time while performing eigenvalue analysis in the time domain. When dynamic/kinematic analysis is the main simulation, then this option will be enabled.

  • Max Number of Mode: Defines the maximum number of mode.

  • Undamped Natural Frequency / Damped Natural Frequency

    • Undamped Natural Frequency: Ignores the damping matrix of the system by the solver. This type focuses on the result of undamped natural frequency.

    • Damped Natural Frequency: Gives eigenvalues including the damping matrix of the system.

  • Cutoff Lower Frequency [Hz]: Set a frequency lower limit to report. All modes smaller than the frequency lower limit are not reported.

  • Output File Name

    • If this option is checked, it allows defining the model output file name before simulation.

    • If this option is not checked, the output file name is the file name. (The default is unchecked.)

  • Hide RecurDyn during Simulation: If this option is checked, the RecurDyn program window is hided during simulation. So, the user can execute the fast analysis. By clicking the right mouse button on the RecurDyn icon at the tray, the user can stop a simulation or activate the RecurDyn main window.

  • Include Static Analysis: If this option is checked, a static analysis is performed prior to a dynamic analysis. For more information, refer to Static Analysis.

  • Gravity: Defines the direction and magnitude of the gravity force.

  • Export RSS: Exports RSS file as current option.
