The FComp interface is used to display fringe component data on the model. It allows the selection of various scalar quantities like strains and stresses that can be fringed.
For shells and beams, such data is stored for different integration points through their thicknesses and cross sections respectively. Upon selecting a component to be fringed, further selection of data at a particular integration point can be made using a simple selection widget with options (Low/Mid/Upp/Max/Ave/Min/IPt/BPt).
By default LS-PrePost will fringe the maximum of all integration point data available.
Stresses and strains in d3plot are in the global coordinate system except when CMPFLG have been used. By default, LS-PrePost will plot the stress and strain as they are written to d3plot. The stress and strain can be plotted in Element, Global, Material or in a User specified coordinate system by changing the "d3plot/Elem/Glob/Mtrl/User" switch but this requires that both the d3plot and the keyword file have been read.
Load data using the button and fringed. This can be from external third party software or element and nodal results output from the Output Interface in Post.

This interface is used to display and plot data for various data over time. It allows selection of various nodal, element, and material quantities from binary files like d3plot, d3dtht etc...
Depending on the type of binary files loaded, the list of available components will change. Time history plotting data from d3plot files is also possible. However, typically a d3plot file contains data for state animation. Consequently the resolution of time history is limited to the number of states in d3plot files. For higher resolution time history plotting, either d3thdt, binout, or various ASCII files should be used.

This interface is used to control all open XY-Plot windows and files. External XY data can be loaded for plotting and/or cross plotting.
Often there is need to plot force vs. deflection response of structures. This requires a force vs. time curve and a deflection vs. time curve. Cross plotting allows users to select deflection from the deflection vs. time curve for the x-axis and force from the force vs. time curve for the y-axis. If the number of points for the 2 curves is not the same, the data is interpolated.
Cross plotting can also be done from plot read in by using the Add button or from XY-plot windows. For cross plotting data from XY-plot windows, the Window option should be activated (The default is the File option).
The format of external XY data can be in Microsoft CSV format or XY data pairs as shown below. In this example, note how the first line of each curve definition defines the number of XY data pairs that follow:
2
0.0,0.0
10.0,20.0

The Follow interface is generally used in conjunction with model animation. Choose either a single point or a plane which will then be frozen and displayed in the center of the screen at all times during the animation.
If the structure is undergoing large rigid body translation or rotation as it is crushing, often it is difficult to understand how the structure is deforming relative to some point in the structure. The Follow Point option allows freezing of the displacement of a follow point (node picked to freeze). Follow Plane is for removing rotations of a body undergoing large rotations, such as tires, a brake rotor, or even an entire vehicle.
Follow plane has an additional option to select parts to freeze rotation as opposed to the whole model (all parts). Follow settings are retained upon exiting this interface and entering another interface. The Reset button disables the follow point and follow plane.

The particle interface is used to simulate the gas generated to inflate airbags. The particles maybe have mass and momentum and act on the surfaces of the bag to expand it. A model can have several bags and the bags surface has porosity and vent holes for the gas to escape.

This interface is used to output model data. During post-processing of binary d3plot files, often there is a need to write entire or partial models out at a particular state in various third party formats as well as in LS_DYNA keyword file format. Such output is often used for conducting analysis like spring-back followed by crash analysis.
In additions to this, the output can be limited to only nodal coordinates, element definitions, nodal velocities, element results, nodal results, shell principal strains, shell element thicknesses, and fluid surfaces. Fluid surfaces are only available if fluid data is present from ALE simulations in d3plot files. Output of a number of states can be saved to a single file by activating the Append option.
