1. In the Dummy Browser, select a body.
2. In the graphics area, click-and-drag the manipulator to interactively modify the position of the selected body.

   
   
   Figure 6.

1. In the Dummy Browser, right-click on a body and select Move Limbs from the context menu.
   The Entity Editor opens.

   
   
   Figure 7.

2. In the Multiple pairs field, select No (apply option to a single node) or Yes (apply option to a set of nodes and targets).
3. If Multiple pairs is set to Yes, click Select pairs to open the Select multi nodes dialog and select nodes and target point pairs.
4. Define a Node of a body.
5. Define the Target location.
6. Click Select Bodies to open the Dummy Bodies DOF dialog and select the bodies and degrees of freedom of the active bodies that will be able to move during automatic positioning.
   Select bodies by activating their corresponding checkbox, or picking them in the graphics area (right-click or left-click to activate/deactivate a body). Lock/unlock degrees of freedom by clicking the lock icon, or by picking the DOF arrows in the graphics area (right-click or left-click to activate/deactivate a DOF).

7. Click Move to start the automatic positioning process.
8. Click Save to save the achieved position.
   A name will be appended to the New position name field.

Auto-contact detection allows you to automatically detect contact between dummy limbs and surrounding structural components during the positioning process. Limb motion is automatically stopped on contact detection.

1. In the Dummy Browser, select the dummy body.
2. In the Entity Editor, select either single contact or multiple contacts that need to be defined by setting Multiple contacts to Yes or No.
3. For each contact, create and assign a set of components in the Contact set part field.
4. In the Gap factor field, type in an appropriate scale factor.
5. Click Close.
   The Contact checkbox is activated for the selected dummy body indicating the contact check is active.

   
   
   Figure 9.

1. In the Dummy Browser, right-click the dummy root name and select Dummy Testdata Positioning from the context menu.
2. Define H-Point location coordinates of the dummy H-Point.
3. Define the Rx global dummy rotation value around the global X-axis.
4. Define the Ry global dummy rotation value around the global Y-axis.
5. Define the Rz global dummy rotation value around the global Z-axis.
6. Select the Creation method.
   • Scan from outputblock: Scans a selected nodal history output keyword (*DATABASE_HISTORY_NODE for LS-DYNA or /TH/NODE for Radioss) and looks for names containing the Name pattern if it is activated. For each node found, a target point is created.
   • From nodes selection (the manual method): Create a target point on all of the selected nodes on the dummy. Each target point is created with a name starting with the Point prefix string.
7. Import the dummy target file. Select a .csv file containing the test measurement coordinates for the target points defined on the dummy.
8. Define Skip lines in csv file on import.
   The number of lines at the beginning of the .csv file that need to be ignored from the reading process.
9. Select Target points on the dummy.
   The tool controls these during the automatic positioning.
10. Select the Targets priority to apply for the control of the target points during the positioning.
11. Select the Export dummy target file where the .csv file, containing the final positioning results for the selected target points, will be exported.
12. Click Create to create the Target points based on the Creation method.
13. Click Import to enable the reading of the .csv file containing the measurements data.
14. Click Select Bodies to select the dummy bodies or DOFs that will be considered during the automatic positioning of the dummy.
15. Click Move to start the automatic positioning process.
16. Click Export to export the .csv file with the final positioning information.
17. Click Close.

1. In the Dummy Browser, right-click on the dummy and select Pre-Simulation > Only Dummy from the context menu.
2. In the PreSimulation Tool dialog, define settings accordingly.
   1. In the PreSimulation type field, select a unit system.

      The unit system will automatically set the default simulation parameters to the correct unit. In any case, you can still modify these values manually.

   2. In the Reference Position field, select the Position that will define the starting position of the dummy in the pre-simulation.
      Per default, the Initial Position of the dummy is selected.
   3. Select the Export Method.
      Single File: Creates the solver deck for the pre-simulation by exporting a single file with the dummy and the load case.
      Pre-defined Include Files: Select the original Dummy include file in its reference position. An include file for the simulation load case and a master file is created, combining the selected dummy include and the load case include.
   4. In the Export File field, enter the pre-simulation deck name and directory.
      Per default, a deck with the name "result" is exported into the ~…/Local/Temp directory.
3. Define PreSimulation Tool Options accordingly.
4. Click Export.

1. In the Dummy Browser, right-click on the dummy and select Pre-Simulation > Dummy with Seat from the context menu.
2. In the PreSimulation Tool dialog, define settings accordingly.
   1. In the PreSimulation type field, select a unit system.
      The unit system will automatically set the default simulation parameters to the correct unit. In any case, you can still modify these values manually.
   2. In the Reference Position field, select the Position that will define the starting position of the dummy in the pre-simulation.
      Per default, the Initial Position of the dummy is selected.
   3. Select the Simulation Method.
      Displacement Based: Creates the needed cable and load case with a control displacement of the cable. This method ensures that the cable displacements are reached at the end of the simulation.
      Force Based: Creates the needed cable and load case with an imposed pre-load in the cables. This method cannot ensure that the final cable displacements are reached at the end of the simulation.
   4. Select the Seat components which are needed to check the intersections with the dummy and create the contacts for the simulation.
   5. Select Fixed nodes on the seat.
   6. Select the dummy direction in which the dummy will be pulled on the seat.
   7. Select the Export Method.
      Single File: Create the solver deck for the pre-simulation by exporting a single file with the dummy and the load case.
      Pre-defined Include Files: Select the original Dummy include file in its reference position. An include file for the simulation load case and a master file is created, combining the selected dummy include and the load case include.
   8. If the Pre-defined Include Files method is selected, select:
      The original dummy include file in its reference position.
      The original Seat include file.
   9. In the Export File field, enter the pre-simulation deck name and directory.
      Per default, a deck with the name "result" is exported into the ~…/Local/Temp directory.
3. Define PreSimulation Tool Options accordingly.
4. Click Export.
   To update the model with simulation results, import the simulation result file, which allows the dummy node's coordinates to be updated and element initial stress state to be defined.

   • For LS-DYNA, click Import dynain File to find the .dynain file.
   • For Radioss, click Import h3d File to find the .h3d file.
