Calculate Quantities for a Dynamic Random Analysis
Use items in this area to specify the type of results Creo Simulate calculates for a dynamic random analysis.
Select the following items if you want Creo Simulate to calculate full results:
• Full RMS results for displacements and stresses—Allows you to display fringe plots for RMS stress and RMS displacement results.
• The following options are available only if the loading is by base excitation:
◦ Mass participation factors—Calculates the modal mass participation factors. This can result in greatly increased computational time.
Mass participation factors are important for determining if sufficient vibration modes obtained from modal analysis are included to ensure accurate results.
◦ Displacements, velocities, accelerations relative to—Calculates results for displacement, velocity, and acceleration results with respect to ground or supports.
You cannot access full results for quantities you do not select here. Creo Simulate calculates all measures valid for an analysis, regardless of your selections here. You can access results for measures through the summary report or by graphing the measure in a results window.

If you select Time/Frequency Eval when you define a dynamic measure, you can access results for this measure only through a results window.
