Graphing/Layout Editor
The Function Display Layout Editor allows you to edit Layouts for use in the Function Display.
It allows you to:
Edit all display objects and their parameters.
Create layouts from scratch. (Only available in R4 & up.)
Creating a New Layout
Currently, you cannot create a new Layout document using the Layout Editor.
Opening a Layout
You can open a layout by using the File Open command in CATIA. Select a Layout file.
Editing a Layout
After opening the Layout, the Layout will be visualized in a new window. You can now edit any parameters in the graphs, axes, etc., and save your changes.
Saving a Layout
Use File Save to save a Layout.
Using a Saved Display Layout
To use the layout in an LMS Virtual.Lab application:
1 Open the desired LMS Virtual.Lab Analysis.
2 Click the New Function Display toolbar button and select the feature you want visualized from the Specification Tree. (See Creating a New Display (on page 6) for more information.)
3 Click the Next button in the New Function Display dialog box that opens.
4 Select <> from the second dialog box.
5 Select the desired file and click the Open button.
6 Click the Finish button.
Layout Editor Toolbar (../mot-tools/layout_editor_toolbar.htm)
Creating a New Display
A Function Display is used to represent the functional relationship between the various parameters from the analysis case or function sets. The New Function Display command is used to create a 2D Function Display.
Please refer to the following topics for additional information on creating and editing the images and layouts.

Restrictions
Capturing a 2D Function Display using the Tools Image Capture tool exposes several problems:
Sometimes the sides of the display are cut off. This is known to happen when the screen resolution has a different aspect ratio than ¾ and when the width of the display is smaller than the height.
When you capture in pixel mode, you have to select Screen quality for the Rendering quality. Other settings will result in a blank screen and you have to close and reopen the display window.
The Save As button in the capture tool may corrupt .eps files. Please use the Print option instead. For this, you have to add the generic postscript printer to your configuration by using File/Printer Setup.
The capture tool in the Function Display window may capture only one part of the contents, when viewed in UI mode. This happens when you have multiple displays in your image/layout. You can work around this by changing your layout to use only one display and put all the graphs in that single display.
Using the Report command on a Function Display may generate blank bitmaps.
On some systems, fonts in the function display may not be rendered correctly in some circumstances. For example, a + sign might be shown as – or |. In general, this means the graphic card’s drivers are not correct, even though using the most current drivers may not always solve the problem.
Overview of Function Display
A Function Display is used to represent the functional relationship between the various parameters from the analysis cases or function sets. The New Function Display command is used to create a 2D Function Display.
To insert a New Function Display:
1 Select an analysis case or function set feature from the Specification Tree, and click the button from the Function Display toolbar.
2 Right-click on an analysis case or function set feature and select New Function Display from the contextual menu.
The New Function Display dialog box will appear.
Select an image type and click the Next button.
The list of layout types will appear. Select a layout type and click the Finish button. A new window will appear with a function display and the Select Data dialog. The contents of the Select Data dialog will vary depending on the analysis cases/ feature sets under consideration.
Clicking the Cancel button will cancel the action of creating a New Function Display. Click the Previous button, to go back to the image type list. According to the analysis cases or function sets, supported image types and layout types will change. This has been discussed in detail in the topic, Image Types and Layout Types (on page 8). Several options are available to edit the function display layout. The details about the layout editing can be found in the topic, Layout Editing (on page 32). The Existing Layouts (on page 59) topic describes on how the existing layout parameters can be used while creating the new images.
Image Types and Layout Types
A 2D display image is used to visualize the functional relationship between parameters. The 2D display image can be plotted in more than one way. The most suitable image type for visualization does depend upon many factors such as application, type of function set or analysis case, function data type etc. LMS Virtual.Lab offers a wide variety of image types. Also different layouts are available for plotting the data. According to the type of function set/ analysis case, available image and layout types will vary. Available image and layout types for different function sets have been discussed separately in this topic. Note that for the analysis cases, available image types will depend on the type of function set for its results. For example, the results of the FRF Synthesis Case are in the form of a transfer function set. Hence the image types available for the FRF Synthesis Case will be same as that of the transfer function set.
Image Types
Different image types available for each function set are given in the following tables.

The image types for the Duplicate Result Set will be same as that of the parent function set.
Following section describes each image type mentioned in the tables above.
The 2D Display option will plot the function on the Y-axis and respective data type on the X-axis. For example the Load Function Set with Time Data as Function Data Type will plot the load on the Y-axis and time on the X-axis as shown in the image below.
This image is used to visualize the status of the load function set/ transfer function set in the form of the matrix plot as shown in the image below. You will observe a value 1, if status of the load/transfer function is ok. In case any load/transfer function is failing, the value will be 0.
This image type uses different colors to represent the variation of the parameters as shown in the image below. The colormap display shows the frequency dependent function for different speed (RPM) values. This is used only for the waterfall of frequency spectra function data type.
This image type uses vertical color bars with different colors to depict a magnitude of the parameter. This is of particular interest while studying the major contribution from many available functions as shown in the image below.
This image type combines two images i.e. Colormap and 2D Display, plotted as vertically tiled in a single window. A 2D Display image will display a variation in the frequency dependent function for selected RPM value/s as shown in the image below. The Colorbar display will be same as explained previously.
This image type combines two images i.e. Color Bars and 2D Display plotted as vertically tiled in a single window. You can study a variation in the frequency dependent function for selected RPM value/s on the Color Bars as well as the 2D Display image.
This is a colormap plot of ordercuts. This image type shows the functional relationship with the frequencies on the X-axis and the speed (RPM) on the Z-axis along with the colorscale axis on the right side of the display as shown in the image below. The Campbell display is useful to ensure that there is no coincidence with the natural frequencies.
This image type shows the transfer functions/crosspower functions on the Y-axis with frequency plotted on the X-axis as shown in the 2D display.
The RMS value is computed for each transfer function and these values are displayed in the matrix display as shown in the image below. The input points (Excitation IDs) are displayed on the X- axis and the output points (Response IDs) are displayed on the Y-axis along with the RMS values on the Z-axis.
The FRAC or PAC value is computed for each transfer function and these values are displayed in the matrix display as shown in the image below. The input points (Excitation IDs) are displayed on the X-axis and the output points (Response IDs) are displayed on the Y-axis along with the FRAC or PAC values on the Z-axis.
The rainflow set is mainly used for visualization.

Otherwise, You can load your own layout by selecting the <> from the list. You are allowed to create your own layout and use it for plotting the respective images. As well you can use the available layouts for plotting the respective images, see Existing Layouts (on page 59) for more details.
Following section describes each layout type mentioned in the table above.
This layout is used to plot the function on the Y-axis and respective data type on the X-axis as shown in the image below.
The Bode plot is a useful way to represent the amplitude and phase of a parameter as a function of frequency. The Bode plots use frequency as the horizontal axis and use two separate plots to display the amplitude and the phase of a function as shown in the image below.
The Nyquist plots display both real and imaginary component on a single plot as shown in the image below. The Nyquist plots have properties that allow you to check whether a system is stable or unstable.
The Polar plots are 2D plots; these are used to plot a function in polar coordinates. In the Polar plot, the radius is equal to the amplitude of a function and angle is equal to the phase angle.
The Vector Plot is used to plot the functions in a vector diagram. It is useful to study the contributions and total response.
The Bar chart is a chart with rectangular bars of lengths equal to the magnitudes of the functions. Sometimes a stretched graphic is used instead of a solid bar. It is shown in the image below.
A matrix plot is used to plot the values of a function between the selected input and output points as shown in the image below.
This layout is useful to study the contribution of the various functions. This plot consists of a function magnitude representation in the form of vertical bars along with colorscale axis on the right side of the display, which displays the colors for amplitude range as shown in the image below.
This layout is used to plot the Colormap images as shown in the image below.
You can create your own layout on any image in the Specification Tree by right clicking on it and selecting the Save As Layout from its contextual menu. Thus it allows you to reuse the available layout you created, see Existing Layouts (on page 59) for more details.
This layout is used to create two images in a single window i.e. colormap and XY plots as shown in the image below, which is useful for comparing the results.
This layout is used to create different images in a single window i.e. colormap and bode plots, which is useful for comparing the results.
This layout is used to create two images in a single window i.e. color bar and XY plots as shown in the image below, which is useful for comparing the results.
This layout is used to create different images in a single window i.e. color bars and bode plots as shown in the image below, which is useful for comparing the results.
Layout Editing
This topic describes different layout editing options. Each layout for a 2D image consists of few basic entities as shown in the image below.
An image layout can be edited for following entities,
Each type of entity editing options are described in detail.
Axis
Double click on the axis (X or Y). A new dialog will appear as shown in the image below. Various editing options for an axis are present according to attributes on each tab. Most of these options can also be accessed by right clicking on the axis and selecting from the contextual menu. Each tab in this dialog box is explained one by one.
Limits
This option defines the limits of the axis according to the lowest and the highest values of the input data, on the respective axis. Thus it allows exactly fitting all the data in the available display area.
This option also defines the limit of the axis according to the lowest and the highest values of the input data, but using the rounded off values of the lowest and the highest values of the data.
This option allows you to specify the Lower and the Upper limits of the axis manually. Selecting the Free option will gray out the Upper field for the respective axis and value for it will be equal to the highest of the input data, as mentioned in the Free limits.
This option uses the lower limit of the input data as the bar chart origin on the Y-axis.
Format
The formatting option allows you to apply a specified format on the respective axis. The available formats for the X-axis in LMS Virtual.Lab are shown in the image below.
For X-axis
The data on the X-axis will be expressed in the linear format.
The data on the X-axis will be expressed in the octave format. For more details on the Octaves, refer Octave Bands (../aco-fem/octave_bands.htm).
The data on the X-axis will be expressed in the decade format. An example of the decade format can be given as, one decade up from 100 Hz is 1000 Hz, and one decade down is 10 Hz.
The data on the X-axis will be expressed in the Power2 format. The increments on this scale will be in the order of power of 2. e.g. 2,4,8…
The available formats for the Y-axis in LMS Virtual.Lab are shown in the image below.
For Y-axis
The data on the Y-axis will be the real part of the input data in complex form.
The data on the Y-axis will be the imaginary part of the input data in complex form.
The data on the Y-axis will be expressed in the phase of complex input data in the degree format. The phase can range from –180 to 180 degrees.
The data on the Y-axis will be expressed in the phase of complex input data in the radian format. The phase can range from –pi-to- pi radians.
The data on the Y-axis will be expressed in the amplitude format for the complex input data.
The amplitude of the data on the Y-axis will be expressed in the logarithmic format.
The amplitude of the data on the Y-axis will be expressed in the decibel (peak) format. The display tries to estimate the original format of the data (Peak or RMS), but sometimes this is not possible. It depends on how the data entered LMS Virtual.Lab. This could result in a display where the y-axis is annoted as Pealk, even though the data is really RMS.
The amplitude of the data on the Y-axis will be expressed in the decibel (RMS) format. The display will always apply a correction factor on the data of sqrt(2) to convert the data from Peak to RMS. The display tries to estimate the original format of the data (Peak or RMS), but sometimes this is not possible. It depends on how the data entered LMS Virtual.Lab. This could result in a display where the RMS conversion is applied twice.
The amplitude of the data on the Y-axis will be expressed in the decibel format. There is no conversion applied from Peak to RMS or vice versa.
Annotation
There are different types of annotations available as shown in the image below, which can be activated/deactivated.

Data references are either expressed in an absolute way, meaning that when you create a new image using this layout, the reference will be resolved to the original data of the source. If you however choose ‘Target’ the references try to resolve the data in a smart way in the new context.
You can load your own layout by selecting the <> from the image layout list as shown in the image below.
You can also use the layouts available in the current CATAnalysis document for plotting a new image. Selecting the Use Layout in new Image option from the contextual menu will pop up the New Image from Layout dialog box as shown in the image below. This layout will be used for a new image. Select a function set/ analysis feature from the Specification Tree, on which you wish to create image. The Attach under and Scenario fields will get filled.
The selected function set/ analysis feature will appear in this field.
This field contains the list of image types, which can be plotted on the selected feature. Select the required image type from the list
Switching on this option will allow you to keep the data references either of source layout or target layout. See Keep Data References section described earlier, for more details.
Selecting Data
Use the Select Data command to add data to the Image.
To execute this command:
1 Make sure a Function Display image is open.
2 Click the Select Data button.
3 Select data using the dialog box.
The Select Data dialog box can be different for each scenario. See your specific Application’s documentation.
Edit Graph Dialog Box
This dialog box allows you to modify the graph display. To open the dialog box, double-click in a blank area (usually white) of the graph. You can also open the dialog box by right-clicking in a blank area of the graph and choosing Options from the contextual menu.
The Units of the Graph have three possible settings:
MKS: Units are shown in MKS (meter kilogram second) system or,
Options Defined: Units will correspond to the settings in the Tools Options dialog.
The Interpretation of some graphs can be set. These options take different views on the data. For example, a BodePlot graph can choose between a Real/Imaginary interpretation and a Phase/Amplitude interpretation.
The Orientation of some graphs can be set. These options assign different orientations to the axes. This allows you to switch horizontal and vertical axes.
The Weighting of some graphs can be set. These options apply different frequency weightings to the data in the graph.
Here you can customize the font and font size of the Graph. You can choose to Inherit the font style from the display. This is the default case. Or, you can set the font style to Custom, and select the desired font and font size. The Make children inherit checkbox will force the text style of all the children of the graph.
Use this tab to edit the title and position of the Graph. You have the option to concatenate all the names of the Data Groups automatically to the Graph title.
Use this tab to change the titles of the Data Groups. You can use your own titles or let the application decide for you. A Data Group represents a collection of Plots.
Graph Context Menu (on page 82)
Display Dialog Box
This dialog box contains all of the parameters for the selected display. To open this dialog, right-click on an empty area of the display window and select Options… from the contextual menu that displays.
Here you can customize the font style of the display. You can choose to inherit the font style from the Image. This is the default case. Or, you can set the font style to Custom, and set the font and font size. This will set the font style of all display objects, as well as the children of the display (if they are in inherit mode). Furthermore, you can force all the Display objects and it's children into inheritance mode by marking the Make children inherit checkbox.
Here you can customize the overall color scheme of the display. It is divided into three parts: the Display area, the Graph area, and the Cursor. The Graph area is the region where all plots are drawn. The Display area is the region outside of the graph area up to the edges of the Window. The Cursor section allows you to change the color of the cursor.
You can choose the colors of these areas using the corresponding drop-down lists. Or, you can select the No background radio button, in which case the backgrounds will be whatever color is set in the application’s Options dialog. The Restore Defaults button will revert the background colors to a white graph area and a light blue display Area. You must click the Apply button for these changes to take effect.
There will be a Graph tab corresponding to every Graph in your display. For example, an Upper/Lower display will have two Graph tabs. See Graph Dialog Box (see "Edit Graph Dialog Box" on page 62).
Display Context Menu (on page 81)
Cursor Dialog Box
Cursors are available by right-clicking a Graph and selecting a cursor. The type of cursors available will depend on the type of graph.

The Input field shows you the input value of the cursor. Here you can precisely set the input value of the cursor. If the cursor is a double-cursor, you can set the input value for the 2 cursors and the delta value (the distance between them).
The Go To combo box allows you to move the cursor to certain points on the data. For example, select Next max and press Go to move the cursor to the next point on the data that is a local maximum.
The Snap to data option restricts the cursor value to actual data points and ignores any interpolation.
Cursor Context Menu
Legend Dialog Box
This dialog box allows you to change the settings for the legend. To open this dialog, right-click on the legend and select Options… from the contextual menu.
Use this tab page to look at all attributes of all plots. This tab page has scrollbars and thus has no limits on the amount of data it can display.
Select the Show entries with no data attached check box to show plots in the display that once existed, but no longer have data attached. You may want to enable this if you want to set colors and line types for these plots. The next time that data is attached to them, it will use the color and line type you set.
Use this tab page to select the attributes you want to see in the legend and the order of these attributes. The list on the left side shows the attributes that are currently hidden. The list on the right side shows the attributes that are currently visible. Use the buttons in the middle to move a selected attribute to the other list. Use the Up and Down buttons to move the selected attribute up or down in the Show Attributes list.
Here you can customize the font and font size of the legend. You can choose to Inherit the font style from the display. This is the default case. Or, you can set the font style to Custom, and select the desired font and font size. The Make children inherit checkbox has no effect since there are no display objects beneath the legend in the hierarchy.
Plot Dialog Box
You use this dialog box to look at the attributes of a curve and change the visualization style. To open this dialog, right-click on a plot in the graph or legend and select Options… from the contextual menu that displays.
Data Tab
With this tab page you can look at all information known about the plot. In the upper part you can see the units of the different variables of the plot. When a plot has more than one result attached, you can change the setting Select Result to choose the result you want to visualize. Finally, you can use the Attributes section to look at all of the attributes that are known for this plot.
Visualization Tab (for 2D plots)
Use this tab page to change the visualization style for a 2D plot. Select the Color, the Dash Style and the Weight to your liking. You can also use a symbol or a barchart to mark the data points.
Visualization Tab (for colormap plots)
Use this tab page to set the visual appearance of the colormap. You can choose between two major settings: Linear Interpolation and Order-based Interpolation. The Linear interpolation is the default and will be used most. You can select if you want to interpolate in the x-direction and/or y-direction. When you choose not to interpolate, the data is stretched to fit the available space.
When you choose to interpolate the data is interpolated between adjacent points. If there are more datapoints in the data than there are pixels, the visualization will make sure that the maximum value is visualized from overlapping datapoints. This means that you will always see the peaks. Keep in mind that if you have more datapoints than pixels, you will loose information and that when you have more pixels than datapoints the color of some pixels is an educated guess.
When drawing a colormap image, LMS Virtual.Lab typically has to interpolate between the datapoints because there are more pixels on screen than there are datapoints. The recommended way to do this is using the Linear interpolation method. However, LMS Virtual.Lab also offers an Order-based Interpolation. The algorithm used for this calculation can be rather slow and depends on an accuracy value. The principle behind this algorithm is as follows:
For each point on the screen, the algorithm determines the order on which the point is located.
After that, the algorithm searches for the closest data points on this order line.
It will use the closest data points to determine the color of the pixel.
Finding the closest points is controlled by the Accuracy value: the larger the number, the more data is taken into account and the longer it takes to find the correct values.
If the Accuracy value is too low, there is not enough data found and the pixel will be drawn white.
If the Accuracy is too large, there is too much data taken into account and the algorithm will take more time to complete.
The value that needs to be used for the Accuracy depends on the actual data. Typically, you should start with a value like 0.0005 and gradually decrease as needed.

Image Dialog Box
Text Style Tab
Here you customize the font style of all elements in the image. You can only select a custom font style, since the Image does not have a parent from which to ask the font style. The Make children inherit checkbox will make sure that the legend, axes and cursors all use the same font style.
Image Properties Tab
You can choose between the default, UI Layout or Paper Layout. Paper Layout allows you to position your display on page, typically for printing purposes. You can also set the width, height, and orientation of the paper. When in Paper Mode, you can resize and position your display using the Resize/Move command (see "Using the Resize/Move Command" on page 85).

Report Dialog Box
The Report command allows you to create an HTML document of an Image or an Image Book. The Report is actually a folder specified by the Name parameter that resides in the directory specified by the Directory parameter. An HTML document will be created in this folder, along with the images files.
You can choose to create the document as HTML or XML, which can both be viewed in a web-browser. In the case of XML, a style-sheet will also be created. You could create your own style- sheet to customize the appearance of the Report.
Copy To Clipboard Dialog Box
The Copy to Windows Clipboard command puts 2D and 3D Images in the windows clipboard.
The dialog box allows you to choose what is put in the clipboard. For 2D Images, you can choose bitmap images or vector images. For 3D Images, you can choose bitmap or 3DXML formats. 3DXML files require the installation of Dassault Systemes 3DXML viewer.
You can also choose to copy the legend text for 2D Images, and the colorscale for 3D Images. When you go to paste into an application such as Word, you should choose Paste special to paste a specific object. For example, in the Paste Special dialog box, you would choose text to paste the legend.
If you have Word installed, you can paste all the selected objects as one Word package.
By clicking the Don’t show this dialog again checkbox, your selections will be remembered for the next time you perform this command. You can modify these settings in the Tools Options LMS Reporting page.

If you want to reset it back to automatic behavior, right-click on the line and select SetFree from the contextual menu that displays. The line position will once again be calculated automatically.
Display Layouts
A Layout is a document that structures graphs in a page. The Layout is used in conjunction with a Data Scenario to visualize an Image when you use the New Function Display command. A Layout contains mark-up for graphs, axes, data groups, legends, and other display objects.
Your application will supply specialized Layouts to use.
It is also possible to edit a Layout in a live Image by using the Layout Editor Toolbar (../mot-tools/layout_editor_toolbar.htm). Furthermore, you can save any Image as a Layout by clicking Save As Layout in the contextual menu of an Image.
Save As Layout Dialog Box (on page 86)
Save As Layout Dialog Box
The Save As Layout command allows you to reuse a Layout for a new Image. A Layout is the mark-up that specifies what is visible in an Image.
For example, consider an Image containing a colormap graph and a barchart graph. This image may also have settings on the axes of the graphs such as scaling and limits. All these settings are a part of a Layout. This command allows you to re-use these settings for use on another Image. These files have a . Layout file extension, but are essentially xml files.
This dialog box also allows you to keep "Data References" that may exist in the original Image. This is a new feature in Virtual.Lab that preserves a description of data. It allows you to specify the data to be shown in the new Image by its inclusion in the Layout. For example, if your original Image contains a specific functions, you could save this layout to create a new Image under a different feature, which would then show the same type of data automatically.
By checking Keep Data References, you indicate that you want the same data to be shown in the new Image that uses this Layout. The option To source indicates that you want to show data from the original Image. Alternatively, the option To target indicates that you want to show the same type of data in the context of the new Image.
Note: the Data References functionality is not available for all features. In the case of features that do not support this functionality, no data will be shown.
New Image From Layout Dialog Box
The Use Layout in New Image command combines the steps of 1: Save As Layout, and 2: New function Display. That is, this command creates a new Image using the current Image’s Layout.
When you start this command, you must first select the feature under which you wish to create a new Image. This selected feature will appear in the Attach under selection box. You must also select a Data Scenario of the feature.

Editing an Axis
You can open a dialog box on an axis by,
Double-clicking on an axis, or
Right-clicking on an axis and selecting Options…
There are four different types of axes:
1 Axes to represent real numbers (see "Axis Representing Real Numbers" on page 88).
2 Axes to represent complex numbers (see "Axis Representing Complex Numbers" on page 93).
3 Axes to represent a colorscale (see "Axis Representing a Colorscale" on page 99).
4 Axes to represent discrete values (see "Axis Representing a Discrete Value" on page 104).
The dialog boxes that appear for these axes consist of different tab pages. Some of these tab pages are re-used for different types of axes; other tab pages are used exclusively for one type of axis.
Axis Representing Real Numbers
For a general overview of axes, see Editing an Axis (on page 88).
This axis is commonly used to represent an argument variable. It's dialog box consists of the following tabs:
1 Limits (see "Limits Tab" on page 91)
2 Format (see "Real Format Tab" on page 91)
3 Title (see "Title Tab" on page 93)
4 Annotation (see "Annotation Tab" on page 89)
5 Text Style (see "Text Style Tab" on page 92)
6 Grid (see "Grid Tab" on page 90)
Annotation Tab
Use this tab to influence how the axis is annotated.
You may wish to include or exclude the limits that are used. If you include them, there is less space on the display to annotate intermediate values, but you can be sure that you always see the current limits.
You may wish to show or hide the axis tick values.
You may wish to show or hide the unit of the axis.
You may wish to show or hide the format of the axis.
You may wish to show or hide the title of the axis.
This setting is only used when you have one of the following axis formats selected: Real, Imaginary, Amplitude, or Linear. The number of divisions will determine how many intermediate values are annotated on the axis. The basis for this setting is optimized limits, even if you set your limits manually or to free. You can set the number of divisions to one of the following:
Automatic: The number of divisions is chosen such that you see as many as possible nice intermediate values between the current limits. If there is not enough space to show all intermediate values, a lower number of intermediate values are chosen. The result is dependent on many factors, including the current limits, the screen resolution, the font and the font size. This setting will make sure that you never see random dropping of intermediate values because of lack of screen space (Recommended).
One, Two, Four, Five, Ten.
This setting is only used when you have one of the following axis formats selected: Real, Imaginary, Amplitude, or Linear. This setting will determine how many ticks you will see between divisions.
You can set this to one of the following:
Automatic: The number of ticks is chosen such that you have somewhere between 10 and 20 ticks on your axis (Recommended).
One, Two, Four, Five, Ten.
Grid Tab
Use this tab page to show or hide grid lines associated to the axis ticks. The color, dash style, and width of the grid lines can be edited here. To edit the tick resolution, see the Annotation Tab (on page 89).
Limits Tab
Use this tab page to set the limits on the axis. You can choose from the following options:
Free Limits: Limits are calculated such that all data exactly fits in the available display area.
Optimized Limits: Limits are calculated such that all data is visible in the display area, but using optimal or rounded-off values.
Fixed Limits: You enter specific upper and lower limits.
Application Defined Limits: Limits are set by the application.
Real Format Tab
Use this tab page to set the format, or scaling of the axis. When dealing with real numbers, you may choose from the following options:
Linear: Set a linear scale.
Decades: Set a logarithmic base 10 scale.
Octaves: Set a logarithmic base 8 scale, using normalized annotation values.
Power2: Set a logarithmic base 2 scale.
Text Style Tab
Use this tab to set the font and font size of the axis. Click the Custom radio button, and then select the Size and Font you wish to see on the axis.
This tab is common to all display objects that use text, and because of this you can inherit text style among a hierarchy of display objects. To set the text style for all axes in a display, you would make sure that all axes are set to Inherit (default), and then set the style in the Text Style tab of the Display dialog box (on page 65). Furthermore, you can override the Custom setting of all objects lower in the hierarchy by marking the Make children inherit check box.
Note: this has no effect for an axis since it is at the bottom of the hierarchy.
Title Tab
Use this tab to edit the title of the axis.

To set the text style for all axes in a display, you would make sure that all axes are set to Inherit (default), and then set the style in the Text Style tab of the Display dialog box (on page 65). Furthermore, you can override the Custom setting of all objects lower in the hierarchy by marking the Make children inherit check box.
Note: this has no effect for an axis since it is at the bottom of the hierarchy.
Title Tab
Use this tab to edit the title of the axis.
Axis Representing a Discrete Value
For a general overview of axes, see Editing an Axis (on page 88).
This axis represents a variable of discrete values. It's dialog box consists of the following tab pages:
1 Discrete Values (see "Discrete Values Tab" on page 106)
2 Annotation (see "Annotation Tab" on page 89)
3 Title (see "Title Tab" on page 93)
4 Text Style (see "Text Style Tab" on page 92)
5 Grid (see "Grid Tab" on page 90)
Annotation Tab
Use this tab to influence how the axis is annotated.
You may wish to include or exclude the limits that are used. If you include them, there is less space on the display to annotate intermediate values, but you can be sure that you always see the current limits.
You may wish to show or hide the axis tick values.
You may wish to show or hide the unit of the axis.
You may wish to show or hide the format of the axis.
You may wish to show or hide the title of the axis.
This setting is only used when you have one of the following axis formats selected: Real, Imaginary, Amplitude, or Linear. The number of divisions will determine how many intermediate values are annotated on the axis. The basis for this setting is optimized limits, even if you set your limits manually or to free. You can set the number of divisions to one of the following:
Automatic: The number of divisions is chosen such that you see as many as possible nice intermediate values between the current limits. If there is not enough space to show all intermediate values, a lower number of intermediate values are chosen. The result is dependent on many factors, including the current limits, the screen resolution, the font and the font size. This setting will make sure that you never see random dropping of intermediate values because of lack of screen space (Recommended).
One, Two, Four, Five, Ten.
This setting is only used when you have one of the following axis formats selected: Real, Imaginary, Amplitude, or Linear. This setting will determine how many ticks you will see between divisions.
You can set this to one of the following:
Automatic: The number of ticks is chosen such that you have somewhere between 10 and 20 ticks on your axis (Recommended).
One, Two, Four, Five, Ten.
Discrete Values Tab
Use this tab page to select the discrete values you want shown. You can move discrete entries between the unselected and selected list boxes.
Grid Tab
Use this tab page to show or hide grid lines associated to the axis ticks. The color, dash style, and width of the grid lines can be edited here. To edit the tick resolution, see the Annotation Tab (on page 89).
Text Style Tab
Use this tab to set the font and font size of the axis. Click the Custom radio button, and then select the Size and Font you wish to see on the axis.
This tab is common to all display objects that use text, and because of this you can inherit text style among a hierarchy of display objects. To set the text style for all axes in a display, you would make sure that all axes are set to Inherit (default), and then set the style in the Text Style tab of the Display dialog box (on page 65). Furthermore, you can override the Custom setting of all objects lower in the hierarchy by marking the Make children inherit check box.
Note: this has no effect for an axis since it is at the bottom of the hierarchy.
Title Tab
Use this tab to edit the title of the axis.
Layout Editor Toolbar
The Layout Editor toolbar contains commands for building and editing a layout. The primary objects in a layout are Graphs and Axes. These are arranged in a grid, called a Display. Pre-built Displays are provided for you to use in your Layout. See the following topics for more information.

The attribute values are set by the application and the user can select which attribute he or she wants to see. To insert such an object, select the Insert Floating Attribute icon from the Layout Editor toolbar and select the graph in which you want to insert it.
The following dialog box will open:
Next, indicate the following:
Plot Index: this number reflects the order in which data is added to the data group.
Data Group: this is application defined and is used to set predictable color schemes for comparing data. Generally, there is only one data group. However, you may have multiple groups.
Attribute: select which attribute you want to see.
Inserting a Legend
To insert a Legend:
1 Click the Insert Legend button.
2 Click in the window where you want to insert the Legend.
3 Choose which graphs you want contained in the Legend.
4 Click OK.
Inserting a Data Group

To edit the layout properties of an object:
1 Click Edit Layout Properties.
2 Select an object to edit (graph, axis, legend).
3 Edit the object.
Inserting a Bitmap
To insert a bitmap image:
1 Click the Insert Bitmap button.
2 Click in the window where you want to insert the bitmap.
3 Choose the image you want to insert using the dialog box.
4 Choose the image size and alignment using the dialog box.
5 Click OK.
Import/Export
For the settings of the Import/Export tab go to the main menu Tools Options. A new dialog box will open as shown below:
In this dialog box, select the tree item Structures and then go to the Import/Export tab. Various settings are available as shown below:
Mesh Structured by: This specifies the structure of the imported mesh. A drop down list as shown below is available from which you can select the type of mesh part. The selected type is automatically set in the Import dialog box in Mesh Splitting option.
create single mesh part: Selecting create single mesh part option will set it as the default setting for importing the model. Please refer below the Import dialog box:
The model is imported as a single mesh part and is not divided into groups as shown below:
create groups under single mesh part: Selecting create groups under single mesh part option will set it as the default setting for importing the model. Please refer below the Import dialog box:
The model is imported as a single mesh part along with the groups if available as shown below:
create multiple meshparts: Selecting create multiple meshparts option will set it as the default setting for importing the model. Please refer below the Import dialog box:
The model is imported as a multiple mesh parts, i.e. it is split as per the property groups as shown below:
Selecting this option will overwrite the Poison’s ratio value with 0.5, irrespective of the value you have entered during material definition, when it is exported to Nastran bulk file.
Select the units for length, mass, time, angle and temperature from the respective drop down lists. These unit settings will be the default unit system while importing the model. Select the option Derive units of forces from unit system if the force unit is to be calculated based on the selected units.
If you unselect the option Derive units of forces from unit system, a separate drop-down list for selecting the unit of force will be available as shown below:
These unit settings are used for exporting the meshes that are not imported but are created in LMS Virtual.Lab. These settings are similar to the import unit system defined above.
Function Display Tab
The display has a number of options, which can be set in the options pane. To schedule this options pane, use the menu Tools Options. In the dialog box that pops up, select General in the feature tree in the left-side of the dialog box. Then select the tab Function Display.
Using this dialog box, you can set:
The default location for layouts stored on disk.
The recent layouts used, depending on a scenario.
The default path to use for exporting data.
The default path for generating reports.
The default precision to use for displaying numbers. In general, the display uses the information in the Units tab page to determine the number of decimals to use for displaying numbers and when to switch to engineering notation. The Units tab has two settings, which are dependent on the unit: the number of decimals to use for read and write. The Units tab does not support some units that are used in Virtual Lab. When that is the case, the defaults filled in for the Function Display will be used. Another option that is not available on the Units tab is the number of decimals to use for showing dB values. You can specify this here as well.
Whether or not to close the display window when it loses focus.
The default colors and text styles used in displays. These settings will only be applied to new layouts.
The default position of graph titles and their contents.

Creating a New Display
A Function Display is used to represent the functional relationship between the various
parameters from the analysis case or function sets. The New Function Display command is used to
create a 2D Function Display.
Please refer to the following topics for additional information on creating and editing the images
and layouts.

Layout Editing (../nov-sysa/layout_editing.htm)
Existing Layouts (on page 59)
Restrictions
Capturing a 2D Function Display using the Tools
Sometimes the sides of the display are cut off. This is known to happen when the screen
resolution has a different aspect ratio than ¾ and when the width of the display is smaller
than the height.
Capture tool exposes several problems:
Image
When you capture in pixel mode, you have to select Screen quality for the Rendering quality.
Other settings will result in a blank screen and you have to close and reopen the display
window.
The Save As button in the capture tool may corrupt .eps files. Please use the Print option
instead. For this, you have to add the generic postscript printer to your configuration by using
File/Printer Setup.
The capture tool in the Function Display window may capture only one part of the contents,
when viewed in UI mode. This happens when you have multiple displays in your
image/layout. You can work around this by changing your layout to use only one display and
put all the graphs in that single display.
Using the Report command on a Function Display may generate blank bitmaps.
On some systems, fonts in the function display may not be rendered correctly in some
circumstances. For example, a + sign might be shown as – or |. In general, this means the graphic
card’s drivers are not correct, even though using the most current drivers may not always solve
the problem.
