In this chapter using HyperView

? ABAQUS systems in HyperView

? Create multiple windows in a page

? Create and overlay contour and vector plots

? Save and use HyperView session files


Result systems in HyperView

The Resolve in section in the Contour and Vector Plot panels allows you to select the system in which you want to plot results. System options include Global, Analysis, Elemental and User-defined.

Global Results in the global coordinate system.

Analysis The associated system to nodes or elements. This option is not relevant for ABAQUS results. Refer to the section in Appendix A titled “Result systems” for additional information.

Elemental The default local systems defined on the surface of planar elements (shell, membrane, etc). This option does not represent the ABAQUS elemental system. Rather, it is similar to the NASTRAN elemental system. Refer to the section in Appendix A titled “Result systems” for additional information.

User-defined Transforms vector results to a user-defined system. This option is available when *SYSTEM, *TRANSFORM or *ORIENTATION systems are read into HV from an INP file.

HyperView cut and paste commands

HyperView has copy and paste commands similar to Microsoft products. They allow you to copy a model and its results to a separate window or page. As well, you can copy several models and their results in one page to another page at one time. You do not have to load files multiple times. You can also copy a window or page to a Word document or PowerPoint presentation.

Exercise 1: Open INP and ODB files

Load the INP file for model data and the ODB file for results data. The *TRANSFORM will be read from the INP file. It is a user-defined system in HyperView.

1. From File in the menu bar, select New and click Yes in the pop-up window.

2. Enter the Load model panel.

3. Click the Load model file browser button and select the file HalfDisc_Complete.inp in the HalfDisc_Run1 folder.

4. Click the Load results file browser button and select the file HalfDisc_Complete.odb in the HalfDisc_Run1 folder.

5. Click Apply.

Exercise 2: Create and compare contour plots

Create two contour plots. The first one represents displacement (disp) results in the global coordinate system. The second one represents disp results in the user-defined system.

Set the view

1. Enter the Entity Attributes panel.

2. Click disc in the components list to select it.

3. Click the Mesh lines button.

Create contour plot of disp results in global system

1. Enter the Contour panel.

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

3. Select X from the drop down menu under Displacement (v).

4. Leave the system type set to Analysis System under Resolved in.

5. Click Apply.

6. Click the traffic light icon to view the contoured animation.

7. Enter the Animation Controls panel.

8. On the panel’s left side, move the slider down to reduce the animation speed.

9. Click the traffic light icon to stop the animation.

10. In the Animation Controls panel, move the slider for Current time: to the far right to view the results for the last increment.

Create a two window page layout

Create a two window page layout to compare the contour plot of disp results in the global system to the next contour plot you create.

1. Click Edit from the menu bar and select Copy Window.

2. Click Page from the menu bar and select Layout….

3. Select the icon from the Page Layout pop-up window.

4. Activate (click in) the right window.

It now has a blue halo around it.

5. Click Edit from the menu bar and select Paste Window.

Create contour plot of disp results in user-defined system

The right window should still be active.

1. Enter the Contour panel.

2. Select User Defined System under Resolved in:.

3. The yellow System selector is active. Click the system in the right window to select it.

4. Click Apply.

Notice the difference between the two contour plots.

Exercise 3: Create and overlay vector plots on contour plots

Create vector plots of disp results and overlay them on contour plots of disp results.

Set the view

1. Enter the Entity Attributes panel.

2. Click disc in the components list to select it.

3. Click the Shaded button to see wire frame of mesh.

4. Click Top in View Controls.

5. Do the above steps for the other window.

Create vector plot of disp results in global system

Create a vector plot of disp results in the global system and overlay it on the contour plot of disp results in the global system.

1. Enter the Vector Plot panel.

2. Activate the left window.

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

4. X under Result type is active. Deactivate Y and Z.

5. The yellow Components selector is active. Select the disk in the left window.

6. Leave the system type set to Analysis System under Resolved in:.

7. Activate Components under Show:.

8. Activate Overlay result display.

9. Click Apply.

Create vector plot of disp results in user-defined system

Create a vector plot of disp results in the user-defined system and overlay it on the contour plot of disp results in the user-defined system. You should still be in the Vector Plot panel.

1. Activate the right window.

2. Displacement (v) is selected for Result type:.

3. X under Result type is active. Deactivate Y and Z.

4. The yellow Components selector is active. Select the disk in the right window.

5. Select User Defined System under Resolved in:.

6. The yellow System selector is active. Select the system in the right window.

7. Activate Components under Show.

8. Activate Overlay result display.

9. Click Apply.

Notice the difference between the two vector plots.

Overview of HyperView session files

A HyperView session (MVW) file is a plain text file with the extension .mvw. Data from the results and model data files is not stored in the session file. Rather, the data files are pointed to from in the MVW file. This helps keep the MVW file small and compact. If you move the data files to a different folder, the MVW file will not be able to find them unless you edit the file pathnames in the MVW file. It is suggested you create the MVW file in the folder containing the data files and always keep the MVW and data files in the same folder.

The MVW file also contains commands to re-create the HyperView session, including window and page layout, custom legend settings, result plots, etc.

Create a MVW file using Save Session File from the File pull down menu in the menu bar. Open the file in HyperView to resume post-processing.

Exercise 5: Save HyperView session as a MVW file

1. From the File pull down menu in the Menu Bar, select Save Session File As….

2. Specify a path and name for the .mvw file you will create and Save.

Post-processing of the half disc analysis is complete.
