Performing Harmonic Analysis

To perform harmonic analysis:

  1. Create a linear dynamic study. Right-click the top icon in the Simulation study tree and select Study. You can define a solid, shell, or mixed mesh study. Select Linear Dynamic, and under Options, click Harmonic . Define the frequency and dynamic properties of the study.
  2. Define material for each solid and shell. To define a material for a solid or shell right-click its icon in the Simulation study tree and select Apply/Edit Material.
  3. Define restraints. Right-click the Fixtures icon in the Simulation study tree and select from the options. You can also apply spring connectors.
  4. Define damping. Right-click the Damping folder in the Simulation study tree and select Edit/Define. You can define modal, composite modal or Rayleigh damping.
  5. Define loads. You can define frequency -dependent force, and pressure loads, uniform and selected base excitations.
  6. Define Result Options. Right-click the Result Options folder in the Simulation study tree and select Edit/Define.
  7. Mesh the model and run the study.
  8. View the results:
    • Double-click an icon in the Results folder to display the associated plot.
    • To define a new plot, right-click the Results folder and select the desired option. You can plot displacements, accelerations, velocities, stresses, strains, and deformations for a specified solution step or extreme values across all solution steps.
    • To define a frequency response plot at a specified node, right-click the Results folder and select Define Response Graph. You can plot stresses, displacements, velocities, and accelerations.
    • To list results, right-click the Results folder and select the desired option. You can list , natural frequencies, mass participation factors, stresses, displacements, accelerations, velocities, strains, and reaction forces.
