Options for controlling the detailed aspects of post-processing can be found in the View Options command. Each graphics window can have its view options modified independent of other views. The number and depth of the var-ious view options is such that a full discussion of each is not possible in this manual. For more information, see Section 8.3, "View Options - PostProcessing" in FEMAP Commands.

Controls whether an additional legend is displayed for deformed or contour views. This legend contains informa-tion about the output set and output vectors which are displayed. You can posiinforma-tion the legend in any of the eight locations. Make certain it does not overlap the view legend or the contour/criteria legend.
Deformed Style View Options
The following options control the deformed plot:
• Deformed Style - determines on-screen scale of deformations.
• Vector Style - controls % of vectors displayed and arrowheads for Deformed Vector Plots as well as color for Deformed Vectors.
• Animated Style - number of frames, delay, and shape of the animation (Sine, Linear, etc.)
• Deformed Model - controls colors for Deformed Style display.
• Undeformed Model - can display or remove the undeformed model, as well as set its color.
• Trace Style - controls labeling and display of trace plots.
Contour Style View Options
• Contour Type - controls type of contour and Render mode levels option (for more information, see "Contour Options" above).
• Contour/Criteria Style - allows choice of solid/filled or line contours, controls data conversion between nodal and elemental data, and controls labeling options.
• Contour/Criteria Levels - controls number and spacing of levels for a contour or criteria plot. You may define your own levels (and colors), or have FEMAP automatically scale the plot.
• Contour/Criteria Legend - controls style, color, and visibility of the contour legend.
• Criteria Limits - selects criteria for criteria plots.
• Beam Diagrams - controls direction of beam diagram plots.
• Criteria-Elements that Pass - controls display of elements and their values that pass criteria.
• Criteria-Elements that Fail - controls display of elements that fail criteria.
• IsoSurface - controls color and mode for isosurface plots.
• IsoLine - controls color and mode for isoline plots.
• Streamline - controls color and mode for streamline plots.
• Contour Vector Style - allows you to choose where vectors are located, whether their lengths are adjusted, and the color of the vectors for the contour vector.

5.10.1.1 FreeBody Plots
Freebody information for an entire body, selected elements, or a specific group of elements can be displayed in FEMAP. The Freebody display can be performed at any time, whether you are showing a deformed and contour plot, or a simple undeformed plot. You can setup and control the Freebody display through the Freebody tool in the PostProcessing Toolbox.
The Freebody tool in the PostProcessing Toolbox is shown here. Following is a general overview of using this command. For more information, see Section 7.2.3.3, "Freebody tool".
The most typical use of this command is to examine the forces across a specific interface in your model to check the load transfer path, examine the results and their validity, and possibly even create loads to drive another analy-sis. To do this, elements should be selected on one side of the interface. In the Freebody tool, element selection (and optionally node selection for “Interface Loads”) is done in the Entities section. When the Entity Selection Mode to “Entity Select”, simply click the Add Elements icon button to use the standard selection dialog box. When the Entity Selection Mode to “Group Select”, choose an existing group from the drop-down list (“-1..Active” will always use the “Active” group).
The picture shown below is a simple example of a freebody diagram using Display Mode set to “Freebody” in the Freebody tool . The eight elements in the two columns on the right of the diagram were selected (could also be placed in a group), and the freebody displayed. The result was a diagram containing the external plate forces at the interface, and the original applied loads on the ends (there were no constraints on this section of the model).
Note: The Freebody Elements and Peripheral Elements in the Freebody Contributions From section will only be available if you have recovered grid point force balance from Nastran. If you are not using Nastran, or have not recovered the grid point force balance, you will only have access to the Applied and Reac-tion loads (including MultiPoint), thereby limiting the overall usefulness of freebody displays.
By turning all options “on” in the Freebody Contributions From section of the Freebody tool, you could check that the total loads summed to zero to verify that equilibrium conditions were met and “leaking” of loads did not occur.
If you change the Display Mode to “Interface Load”, you then will want to specify a Location to calculate the Total Force and Total Moment of the force balance at a particular point in space.
You could also examine results using component vectors and/or in any desired coordinate system. If you wanted to create loads at particular locations to replace portions of your model, you could employ the Model, Load, From Freebody command to automatically create these loads.
Freebody View Options
There are several view options to control the overall display:
• Freebody - overall on/off for Freebody display and Label options (labels appear at Location of “Total” vectors).
• Freebody Node Markers - controls Color Mode and Symbol Size of the node markers.
• Freebody Vectors - controls the Length, Label Mode, and Label Format of all freebody vectors and whether their lengths are adjusted.
• Freebody Total Force/Freebody Total Moment - specify the Color Mode, Vector Style, and Factor
• Freebody Nodal Force/Freebody Nodal Moment - specify the Color Mode, Vector Style, and Factor
5.10.2 XY Style
FEMAP can also provide XY plots of results. Just like the deformed and contour options discussed above, View Select controls whether an XY plot is displayed, and what type of XY plot to display.
The available types are:
•XY vs. ID - Plots XY data as a function of ID number for an output vector in one out-put set.
•XY vs. Set - Plots XY data versus the output set number for an output vector across several output sets.
•XY vs. Set Value - Similar to XY vs. Set except uses output set value for X.
•XY vs. Position - Plots XY data versus the position of nodes or elements in an axis direction for an output vector in one output set.
•XY as a Function - Plots XY data for functions. Not a Post-Processing option.
The XY Functions button displays the Select Multiple Functions for View dialog box which is used to select the function(s) (You can choose up to 9 to display) that will be displayed when you choose the XY of Function display style. Even though this is obviously an XY style of plot, you must choose the function(s) to be displayed from this dialog because it is a display of model information, not always post-processing information like all other XY plot-ting styles. Showing multiple functions may be helpful when comparing such things as Input PSD functions, Stress
FEMAP and stored as functions.
