Result file

In the Result file section, select a .pch file and click Load.  Upon reading the file, other fields on the Load tab are populated.

File ID

Select a file ID from 1 through 8.  A total of  eight files can be overlayed at each time.

File action

Select an action from the drop-down menu to apply to the file ID:

File path

Select an OptiStruct or Nastran .pch file that contains one or more response subcase data.

Respone/Subcase Control 1 and Control 2

The following fields are available under Response/Subcase.  Once the result selection options are complete, click Load Response to further investigate the participations.

Subcase

Select an analysis subcase from the drop-down menu.  Use the up and down arrow buttons to go to the next item in the list.

Response

Select the grid ID and component of the response from the drop-down menu.  Use the up and down arrow buttons to go to the next item in the list.

Scale

The following options are available under Scale:

Linear

Plots the linear values.

Logarithmic

Plots the values in logarithmic scale. With this scale, data points are spread out more, which makes it easier to view.

dB10

10 logarithmic of the participation value over the reference value.

dB20

20 logarithmic of the participation value over the reference value. For acoustic responses, the reference pressure is 20E-12 MPa.

Weighting

A – A-weighting is used to define equal loudness sound pressure levels.

B – B-weighting is used to define equal loudness sound pressure levels.

C – C-weighting is used to define equal loudness sound pressure levels.

U – U-weighting is used to define equal loudness sound pressure levels.

Unit

The Unit option allows you to display unit information in the axes labels.  Place a check mark in the Unit box to enable this feature; remove it to disable this feature.  The entity units are derived from unit sets for Time, Length and Force.  For example, the acceleration is m/s2 if Time is set to seconds (s), Length is set to meters (m), and Force is set to Newtons (N).

Plot layout

Allows you to select how the plots are displayed in the window.

Update current layout

Current plot/layout is updated in the active window.

Plot response in a new page

The response is plotted into a new window on a new page.

Copy current layout in new page

Current plot/layout is copied and placed into a new window on a new page.

Layout Definitions

Saves the diagnostic layout for responses.

Import/export the layout definitions in the template files.

Display

Do not show phase - Hides the phase values on the plot.

Show phase - Displays the phase values on the plot.

Plot Result File

Click on a numbered button to toggle the response display from the file.  The plot line color matches the numbered button color.

Concern frequency Information

The concern frequencies are populated once diagnostic results are loaded.
