Post-processing for crashing tubes analysis

In this chapter using HyperView

Extract data from results animation using the Measure panel

Create a HyperView report template to automate your post-processing work from the Reports panel

Overview of extracting data from results animation

Use the Measure panel to measure position at any given time frame, the relative displacement of nodes, relative distance between nodes, the relative angle between nodes, and the angle between nodes. The panel also allows you to generate XY plots in the Plot window from the measures. The Animation window and Plot window are in synch when they animate.

One additional measure group type is available if a contour has been applied. If a contour consists of nodal results then it is Nodal Result. If a contour consists of elemental results then it is Elemental Result.

Overview of HyperView report templates

After setting up the initial session, use the report template functionality to reproduce the session using different result files.

A report template is a special form of the HyperView session file that parameterizes the data files used in the session. Using the template file along with the Report Wizard, this entire session can be duplicated for a different set of results data. For this chapter, a results data set from a similar run is already available in the CrashTubes_Run2 folder.

Overview of the Reports panel

The Reports panel works in conjunction with the report template to generate a HyperView session. Once a report definition template is opened, all of the parameters defined in the template can be set by the user. By default, all of the data files used in the session are set up as parameters when the template was written.

Additional parameters can be defined for any entity or attribute in the session. For more information, see the online help under HyperView / MotionScript Refrence / Report Definition Files.

Exercise 1: Load INP and ODB files

Load the INP file for model data and the ODB file for results data. The *ORIENTATION in the INP file is read into HyperView as a User Defined System.

1. Start a new session by selecting New from the File drop down menu and clicking Yes to the confirmation message.

2. Enter the Load model panel.

3. Click the Load model file browser button and select the file CrashTubes_Complete.inp.

4. Click the Load results file browser button and select the file CrashTubes_Complete.odb.

5. Click Apply.

Exercise 2: Contour and animate displacement results

1. Enter the Contour panel.

2. Select Displacement (v) under Result type:.

3. Select Mag under Displacement (v).

4. Click Apply.

5. Set the Animation mode to Transient using the selector on the right side of the tool bar.

6. Start the animation by clicking the traffic light icon.

7. Enter the Animation Controls panel and move the slider on the menu’s left side to slow down the animation.

8. Stop the animation by clicking the traffic light icon.

Exercise 3: Contour and animate von mises stress in layer 3

Create a contour plot of von mises stress results for shell element layer 3. Remember, section points 1, 2, 3, 4 and 5 were specified for *ELEMENT OUTPUT.

1. Enter the Contour panel.

2. Select S-Stress components IP (s) under Result type.

3. Select Mises under S-Stress components IP (s).

4. Click the switch to the right of Mises and select SectionPoint 3.

5. Activate Display corner data.

6. Click Apply.

7. Set the Animation mode to Transient using the selector on the right side of the tool bar.

8. Start the animation by clicking the traffic light icon.

9. Enter the Animation Controls panel and move the slider on the menu’s left side to slow down the animation.

10. Stop the animation by clicking the traffic light icon.
