Define Acceleration Plot

The Define Acceleration Plot PropertyManager allows you to plot acceleration results for linear and nonlinear dynamic studies.

Display

• Component . Select an acceleration component . Directions are based on the global coordinate system.

• Units . Select a unit for the acceleration plot.

Advanced Options

• Show PSD value. When checked, the PSD values are shown for a particular solution step. Otherwise, the RMS values across the whole frequency range are shown.

Plot Step

• Plot for Single Step . Select this option to plot the results at one solution step.

• . Displays the time corresponding to the selected solution step.

• Displays the frequency corresponding to the selected plot step. Available for harmonic and random vibration studies.

• Plot Step . Sets the solution step number for the plot.

• Plot Bounds across All Steps . Select this option to plot extreme values regardless of the solution step they occur at.

• Maximum. Displays the maximum algebraic values (envelope plot) across all solution steps.

• Minimum. Displays the minimum algebraic values (envelope plot) across all solution steps.

• Absolute maximum. Displays the absolute maximum values (envelope plot ) across all solution steps.

Acceleration results are available for nodes only.

Deformed Shape

If checked, the selected acceleration component is plotted on the deformed shape of the model.

• Automatic. Displays the default Scale Factor that the program uses to scale the largest deformation to 10% of the largest dimension of the smallest box that surrounds the model.

• True scale. Displays the actual deformed shape of the model (Scale Factor is 1.0).

• User defined. Allows you to enter your own Scale Factor . In most cases, a larger scale factor helps to appreciate the deflection.

Property

• Include title text. If checked, type a custom title for the plot.

• Associate plot with name view orientation. Allows you to associate a predefined view orientation with the active plot.
