Tutorial – 1 Basic introduction to HyperWorks Student Edition. Getting started with HyperWorks, Import, Export, Open, Save, Working with panels, Rotate, Zoom, pan… etc .
Tools The HyperMesh – Student Edition interface contains several areas. Each is described below.
Title Bar
Menu bar Toolbars
Graphics Area
Main Menu Pages
Tab Area
Main Menu
Command Window Status Bar
Title bar
The bar across the top of the interface is the title bar. It contains the version of HyperMesh that you are running and the name of the file you are working on.
Menu Bar
Located just under the title bar. Like the pull-down menus in many graphical user interface applications, these menus "drop down" a list of options when clicked. Use these options to a ccess different areas of HyperMesh functionality.
Toolbars
Located around the graphics area, these buttons pr ovide quick access to commonly -used functions, such as changing display options. They can now be dragged and placed at top or side of the graphics area.
Tab Area
The Tab Area is so named because various special ized tools display on tabs i n this area of the int erface. Two such examples are the Model Browser and the Utility Menu.
Graphics area
The Model tab contains the Model Browser. This tool displays the contents of a model in a hierarchical tree format. It can be used to create and edit many types of entities, and also to organize them and control their display status. The Utility Menu contains four pages of tools that perform various functions, accessed via buttons at the bottom of the menu. By default, the Disp page is active; the Disp page tools control how a model is displayed in the graphics area. The other pages available are QA/Model (element checking tools), Geom/Mesh (tools for working with a model’s geometry as well as for creating and editing meshes), and User (custom tools you create). The content of the Utility tab changes based upon the selected user profile.
The graphics area under the title bar is the display area for your model. You can interact with the model in threedimensional space in real time. In addition to viewing the model, entities can be selected interactively from the graphics area.
Main menu
The main menu displays for each page t he functions available on that page. You access those functions by clicking on the button corresponding to the function you wish to use.
Main menu pages
The main menu pages menu divides the main menu into groups of r elated functions. Only one page of t he main menu is displayed at a time. The Geom page contains functions for creating and editing geometry. The 1D, 2D, and 3D pages contain element creation and editing t ools grouped according to element type. The Analysis page contains functions to set up t he analysis problem and define the boundary conditions. The Tool page contains miscellaneous tools and model checking functions. The Post page contains post-processing functions.
Command window
You can type HyperMesh commands directly into t his text box and execute them instead of using the HyperMesh graphical user interface. This window is not displayed by default, but can be opened via the View menu.
Status bar
The status bar is located at the bottom of the screen. The left end of the status bar displays your current location in the main menu. By default, Geometry is displayed. The three fields on the right side of the status bar display the current Include file, current component collector, and current load collector. All three fields are blank by default. As you work in HyperMesh, any warning or error messages also display in the status bar. Warning messages appear in green and error messages appear in red.
Hint:
You can hold the left mouse button down on top of a panel to see a description for it in the status bar.

Controlling the Display Retrieve the HyperMesh model file, bumper.hm. When performing finite element modeling and analysis setup, it is important to be able to view the model from different vantage points and control the visibility of entities. You may need to rotate the model to understand the shape, zoom in to view details more closely, or hide specifi c parts of the model so other parts can be seen. Sometimes a shaded view i s best, while other times, a wireframe view allows you work on details inside the model. HyperMesh has many functions to help you control the view, visibility, and display of entities
Manipulate the model view using the mouse controls The CTRL + mouse keys are used to rotate the model, change the center of rot ation, zoom, fit, and pan 1.
Move the mouse pointer into the graphics a rea.
2.
Press the CTRL key + left mouse button and move the mouse around. The model rotates with the movement of the mouse. A small white square appears in the middle of the graphics area, indicating the center of the rotation. Release the left mouse button and press it again to rotate the model in a different direction.
3.
Press the CTRL key and quick -click the left mouse button anywhere on the model. The center of rotation square appears near where you clicked HyperMesh searches for one of the following conditions in the listed order and relocates the center of rotation at or near the first condition identified (if none of the conditions are met, the center of rotation is relocated to the center of the screen):
A nearby node or surface vertex.
A nearby surface edge to project onto.
A nearby geometry surface or shaded element.
4.
Press the CTRL key + left mouse button to rotate the model and view the change in rotation behaviour.
5.
Press the CTRL key and quick-click the left mouse button anywhere in the graphics area, except for on the model. The center of rotation square is relocated to the center of the screen.
6.
Press the CTRL key + left mouse button to rotate the model and observe the change in rotation behaviour.
7.
Press the CTRL key + middle mouse button, move the mouse around, and then release the mouse button. A white line is drawn along the path of the mouse movement. When the mouse button is released, HyperMesh zooms in on the portion of the model where the line was drawn. You can also simply draw a line to zoom in on a portion of the model.
8.
Press the CTRL key + quick-click the middle mouse button. The model is fitted to the graphics area.
9.
Press the CTRL key and spin the mouse wheel. The model zooms in or out depending on which direction you spin the mouse wheel.
10. Move the mouse pointer to a different location in the graphics area and repeat #9. Notice the model zooms in or out from where the mouse handle is located. 11. Press the CTRL key + quick-click the middle mouse button to fit the model to the graphics area. 12. Press the CTRL key + right mouse button and move the mouse around. The model is panned (translated) according to the mouse movement.
Control the display of components using the toolbar 1.
On the Visualization toolbar, click Shaded Elements and Mesh Lines ,
.
2.
Notice the shell elements now have been shaded.
3.
Right-click Shaded Elements and Mesh Lines ,
4.
Notice now the elements shading does not show any mesh lines. Only feature lines are di splayed.
5.
Right-click Shaded Elements and Feature Lines ,
6.
Notice now the feature lines are also removed from the display.
7.
Click Wireframe Elements (Skin Only) ,
, and switch to Shaded Elements and Feature Lines ,
, to access Shaded Elements,
.
.
, to return to the wireframe shading mode.
Control the display of entities using the Mask panel to open the Mask panel.
1.
Click Mask
2.
Go to the mask subpanel if not already there.
3.
With the elems selector active, select elems >> by collector.
4.
Select the component, mid1.
5.
Click select to complete the selection of components.
6.
From the graphics area, manually select a few elements in the center (blue) component.
7.
Click mask to mask the elements. The elements in the mid1 component and the elements you selected from the graphics a rea are no longer displayed.
8.
In the Model Browser, notice that the elements ( ) for the components center and mid1 are still displayed. Their display icons indicate that they are activated even though some or all of the elements in these components are masked (hidden).
9.
In the Mask panel, click unmask all , or on the Display toolbar click unmask all (
).
All the elements in the components, center and mid1, are visible again. Notice the elements in the other components are not displayed. This is because these components are not activ e in the Display panel. 10. Click return to exit to the main menu.
