Bar

Allows you to plot modal/panel participations to an acoustic or structural response on a bar chart.

Enter a specific frequency in the Specific Frequency field, or use the slider bar to select a frequency value.  When you use the slider bar to select a frequency, a red line is displayed on the response plot and is dragged simultaneously as you drag the slider bar.

Complex component

Projected - Plots scalar participation values after projection to the response. The positive values are in-phase with the response and the negative values are out-of-phase.  Available for Bar plots only.

Magnitude - Plots the magnitude of the complex participation values. Available for Bar, Sand Dune and 3D Surface plots only.

Magnitude-Phase - Plots the magnitude and phase of the complex participation values.  Available for Polar, 3D Polar,
and 2D Line plots only.

Abs of Projected - Plots the absolute value of the the complex participations after projection to the response.  Available for 2D Line, Sand Dune, and 3D Surface plots only.

Rank by

Abs of Projected - Contributors are ranked by the area under the curve of the absolute values of their participations projected to the response.

Magnitude - Contributors are ranked by the area under the curve of the magnitude of their participations.

Abs of Projected RSS - Contributors are ranked by the root sum of squares of their participations at selected frequencies projected to the response.

Magnitude RSS - Contributors are ranked by the root sum of squares of the magnitude of their participations at selected frequencies.

A-Weighted RSS - Contributors are ranked by the root sum of squares of the A-weighted complex component (abs of projected or magnitude, depending on user selection) of their participations at selected frequencies.

Display Options

The Display Options dialog allows you to customize the plot, including scale, weighting, and the plot layout.

Polar

Creates a 2D polar plot of the contributing modes/panels at a specific frequency.

Enter a specific frequency in the Specific frequency field, or use the slider bar to select a frequency value.  When you use the slider bar to select a frequency, a red line is displayed on the response plot and is dragged simultaneously as you drag the slider bar.

All other options are similar to those for the Bar plot.

2D Line

Creates a plot of modal/panel participations to an acoustic or structural response on a 2D line plot (overlay).

Frequency range indicates the available range, based on your PCH or F06 file.

Using the From and To fields, you can customize your own frequency band.

All other options are similar to those for the Bar plot.

Sand Dune

Creates a plot of modal/panel participations to an acoustic or structural response on a Sand Dune plot, in which each contributor’s value is stacked on top of the previous ones, thus generating a distinct color band for easy identification.

Frequency range indicates the available range, based on your PCH or F06 file.

Using the From and To fields, you can customize your own frequency band.

3D Polar

Creates a plot of modal/panel participations to an acoustic or structural response on a 3D polar plot.

Frequency range indicates the available range, based on your PFMODE.PCH or .f06 file.

Using the From and To fields, you can customize your own frequency band.

3D Bar Plot

Creates a plot of modal/panel participations to a 3D Bar plot.

Frequency range indicates the available range, based on your PCH or F06 file.

Using the From and To fields, you can customize your own frequency band.

3D Surface Plot

Creates a plot of modal/panel participations to a 3D Surface plot.

Frequency range indicates the available range, based on your PCH or F06 file.
