Calculate Quantities for a Dynamic Time Analysis
Use the Calculate area on the Output tab to specify the type of results to be calculated for a dynamic time analysis.
Select one of the following check boxes if you want Creo Simulate to calculate full results:
Stresses—Calculates stresses. If you do not need stress results, clear this check box to save disk space and drastically reduce analysis time.
Rotations—Calculates the rotational degrees of freedom of beams and shells over the entire model.
Rotations are not calculated if your model consists only of 3D solid, 2D solid, or 2D plate elements, even if this check box is selected. Rotations are always zero for these element types.
Ply Stresses—Calculates the ply-by-ply stress results. This check box is only for models that have laminate shell properties defined.
The following options are available on the dynamic time analysis dialog box only if 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.
