Potato Plot

Automatically generates potato plots for subcase screening.

A potato plot uses the *.fbd file from the Resultant Force and Moment (RF&M) utility as its input file. You can select the sections and loadsteps from the *.fbd file to include in the plot, as well as several other plot options described below.

Load File

Click the file open icon, , in the .fbd field to select the path and name of the RF&M utility's FBD file that contains the data to generate the plot.

Sections

Displays all cross-sections available in the selected FBD file. The Sections selector allows you to specify which cross-sections in the selected FBD file to include in the plot. Multiple cross-sections can be selected using the standard Ctrl/Shift functionality.

The following filter buttons allow for additional selection control.


Search for a particular filename.


Select all sections or subcases listed.


Exchanges the currently selected items for the unselected items in the list.


Deselects all selected items.

Loadsteps

Lists all loadsteps available in the selected FBD file. The loadstep selector allows you to specify which loadsteps in the selected FBD file to include in the plot. Multiple cross-sections can be selected using the standard Ctrl/Shift functionality.

The Loadsteps filter buttons allow for additional selection methods (see above).

Potato Plots

From this tab, you can define the X and Y components for the plot. Options include:
X component and Y component
Each plot is defined by selecting one X and one Y component and by clicking Add plot. Available X and Y components include Fx, Fy, Fz, Mx, My, Mz, Fr, and Mr. Any plots created are added to the table on the right.
Delete plot
To delete a plot, highlight one or more plots in the table and click Delete plot.
Note: If a plot with the same X and Y components already exist, a duplicate plot is not added to the table.

Plot Titles

Define a title and subtitle for all generated plots.

Plot Options

Define several options for generating plots. They include:
Reverse sign
Allows you to reverse the sign (+/-) of the output at one or more cross-sections. The top drop-down menu is populated with the list of selected cross-sections.
Reverse Types
The bottom drop-down menu lists the type of reverse to be performed. Options include:
Reverse selected section
Reverses the sign of the output at only the selected section.
Reverse all but selected section
Reverses the sign of the output at all sections but the selected one.
Reverse all
Reverses the output at all sections.
Reverse none
Does not reverse any data.
Plot points
Currently, all interior and boundary points are plotted. Future releases will enable all options.
Label points
Allows you choose how to label each point in the plot. Options include:
Label points (Name)
Labels each point with the name of the subcase from which it's generated.
Label points (ID)
Labels each point with the ID of the subcase from which it's generated.
Note: If both options are selected, the format defaults Name (ID).
