Relative Displacement

Allows you to transform vector results from a time history or animation result files according to a coordinate system defined by three nodes from the same result file.

Select Vehicle Safety Tools > Relative Displacement to display the Relative Displacement browser tab.

This tool allows you to see the relative displacements in the higher sampling rate normally provided by time history results.

File type
From the drop-down menu, select a supported file type.
  • Radioss - TH
  • LS-DYNA - nodout
  • LS-DYNA - d3plot
  • LS-DYNA - binout
  • Radioss - A001
  • Hyper 3D - H3D
File name
After selecting a file type, use the file browser button to locate your file and click Load.
The remaining fields in the browser are populated upon loading your file.
Loaded files
If you load another supported file type from the Build Plots panel, that file is also displayed on a drop-down list in this field, along with the file you loaded directly from the browser tab. If you select the file you loaded from the Build Plots panel, the results from that file are automatically populated in the Relative Displacement browser tab and you can then plot the displacement using those results.
Ref coordinate system
From the Plane Type drop-down menu, select OXY, OYZ, or OZX as your coordinate system.
For N1, N2, and N3, select the reference points from the corresponding drop-down list.
Under Filter, in the N1:, N2: and N3: fields, you can enter a values to filter the options contained in the corresponding drop-down lists. For example, for N1:, if you enter "870", only the results that contain "870" in the point name are displayed. This is helpful if you have a large list of nodal points to search in the list.
Result request
Select the point for which you want to plot the relative displacement with respect to the three points you selected in the reference coordinate system section.
Enter values to filter the result types listed below.
  • Click Select All, , to select all items in the list.
  • Click Select None, , to clear any existing selections.
  • Click Reverse, , to reverse the current selections.
Result component
Select one of the following options to plot the X, Y, Z, or relative displacement type:
  • X Displacement
  • Y Displacement
  • Z Displacement
  • Relative Displacement
Plot window
New Plot
Plots your results in a new plot.
