To access, select fld plots on the main page to use this panel.

FLD plots allow you to determine the areas of the model at which failure may occur. Typically, elements above the FLD curve are considered to fail by splitting.

How do I...

1.	Activate one or more of the check boxes to display different viewing options:

fldplot

2.	Select an element in the model to highlight the corresponding point in the plot.

The location on the plot, element ID, and number of points in the plot are displayed on the panel.

3.	Select a point on the plot to highlight the element in the model, and display the location on the curve, element ID, and number of points in the model on the panel.

4.	Click FLD contour to locate the different zones relative to the FLD curves.

A color contour of the model relative to FLD is displayed. Red indicates failure by splitting zones, yellow indicates marginal or potential failure by splitting zones, dark blue indicates high wrinkle potential zones, light blue indicates moderate wrinkle potential zones, and green indicates safe zones. The different zones are described under the color contour legend.

1.	Click the FLD Plots panel.

project= should point to the current project name with the complete path.

2.	By default, all components used for analysis should be selected for FLD plots. You may choose to deselect some of the components from the comps selection.

3.	Click create FLD.

The FLD plots, with the elemental major and minor strains, are plotted with all of the associated curves (FLD marginal, compression line, tension line, -45 (draw) line, and +45 (stretch) line). All of the components selected will be displayed with one FLD plot per component. The plots are arranged on the graphic window in the order of the component IDs from the top, upper right-hand corner downwards.

The colors of the plotted points on the FLD (corresponding to element major and minor strain), are based on their relative position with respect to the FLC as follows:

Color	Description
Red:	All points above the FLC
Yellow:	All points between the FLC and the "FLC marginal"
Green:	All points between the "FLC marginal" and the "-45 (draw) line" and the "+45 (stretch) line"
Light Blue:	All points between the "-45 (draw) line" and the "compression line"
Dark Blue:	All points on the left-hand side of the "compression line"

The model with the displayed components is resized so that it does not overlap with the FLD plot area.

1.	Click FLD contour.

The formability contour is displayed for all selected components. You may choose to deselect some of the components from the comps selection. All of the components selected will be displayed with the formability contour along with the corresponding FLD plots. The smoothed out colors of the elements are based on their strain levels with respect to the FLC as follows:

Color	Description
Red:	All points above the FLC
Yellow:	All points between the FLC and the "FLC marginal"
Green:	All points between the "FLC marginal" and the "-45 (draw) line" and the "+45 (stretch) line"
Light Blue:	All points between the "-45 (draw) line" and the "compression line"
Dark Blue:	All points on the left-hand side of the "compression line"

The legend below describes the regions corresponding to the different colors as follows:

Color	Description
Red:	Failure
Yellow:	Marginal_F
Green:	Safe
Light Blue:	Marginal_W
Dark Blue:	Wrinkle

1.	After creating the FLD plots and contour, click on the model. The element at the cursor location and the plotted point corresponding to it under the FLD are highlighted.

2.	Click on a point under an FLD plot. The plotted point at the cursor location and the element corresponding to that plotted point are highlighted.
