global model parameters accessed by several different

panels. These parameters remain constant until changed.

Use this panel to specify which template file you want to

use. The panel controls which collectors (a collection of

data pertainent to a given entity and handled as a group)

are active. Any entities you create are stored in the active

collectors. (keyboard hotkey g)

help allows you to access the on-line help. On panels, you

obtain context sensitive help describing the functions of

the panel with links to various terms described on the

panel. (keyboard hotkey: h)

disp allows you to access the display panel where you can

select which collectors are displayed on the screen.

(keyboard hotkey: d)

allows you to view the HyperMesh model structure by

organizing assemblies, components, multibodies,

properties, materials, and beamsectcols into a tree-like

display.

vis is available when you use the performance graphics

engine. It allows you to assign a set of display attributes

to each component of your model.

Page menu

The Page menu allows you to select different sets of functions.

The Geom page contains functions having to do with the creation and editing

of geometry.

The 1D, 2D, and 3D pages contain element creation and editing tools grouped

according to element type.

The BCs page (boundary conditions) contains functions to set up the analysis

problem and define the boundary conditions.

The Tool page contains miscellaneous tools and model checking functions.

The Post page contains post-processing functions.

Panel menu

The Panel menu displays for each page the functions available on that page.

You access those functions by clicking on the button corresponding to the

function you wish to use.

Note

Some functions are located on several pages. For example most of the functions in the

leftmost column (files, collectors, etc) can be accessed from each of the seven pages.

Using the on-line help

In this section access the on-line help for the geom cleanup panel and get familiar with the

HyperMesh help system.

1. From the main menu, select the Geom page.

2. Go to the geom cleanup panel.

This panel provides tools to modify your geometry data and prepare it for meshing operations.

3. From the permanent menu, click help.

A help window describing the basics of the geom cleanup panel displays. This help page

contains a description of the panel as well as links to the help pages for its various sub-panels,

and How Do I’s to assist you in using the panel’s functions.

4. Review the content of the help.

The HyperMesh online help system is context sensitive. Whenever you press the help button

while you are in panel, you will be taken directly to the help page for that panel.

5. Click the edges link.

This takes you to a new help topic describing the edges sub-panel of the geom cleanup panel.

6. To return to the previous help topic, click the Back button located at the top of the page.

This takes you back to the page you started from. Notice how the Back button is therefore grayed

out.

Navigation through the on-line can be done following links and using the Back button as was just

done here. You can also navigate through pre-defined browse string using the double-arrow

browse buttons,

. Browse strings are goupings of topics that have a relationship

between them, whether they complete one another in covering a specific subject, or are simply

part of a broader concept.

The browse buttons are only active for topics that belong to a browse string. For example, the

current topic (geom cleanup panel help) does not belong to any browse string as these arrows

are currently disabled.

7. Go down the geom cleanup help page until you reach the Note.

This note provides provisions regarding the actual appearance of this panel, depending on the

user profile currently loaded in HyperMesh.

8. Click the link User Profiles.

A new help topic appears. Notice how the double-arrows are now active to go forward.

9. Browse forward in the browse string using the forward double arrows.

Once you are passed the first topic of the string, the back double-arrows are active and allow you

to go back to the previous page of the browse string.

While the Back button takes you to the previously displayed page, the browse buttons allow for

navigation within a set sequence of topics only. In this particular example, the browse button

would only allow you to browse through pages that belong to the User Profiles browse string and

would not take you back to the geom cleanup panel help, which does not belong to any browse

string. Using the Back button would take you back to this topic after taking you through all the

topics you have visited since you started there.

Once the help is launched, the entire help system is also available using the help contents, index

and find tabs.

10. Click the index tab and type geom cleanup at the prompt on the Index tab of the Help Topics

dialog that popped up.

The help system returns matches for the text you typed.

11. Select geom cleanup panel from the list and click Display.

HyperMesh 7.0 Tutorials - HM-1000 Altair Engineering

Proprietary Information of Altair Engineering.

This takes you again to the geom cleanup panel help, although you are not back at the starting

point of the history of pages as signified by the Back button being available. Using the Index, you

simply made a jump to a new page.

12. Click Contents at the top of the window to bring up the Help Topics dialog and the Contents

tab.

This tab allows you to review the table of content of the help system for the HyperWorks

applications installed at your site. This is a tree-like representation of the content of the help with

books representing groupings of books and/or topics (represented with a question mark).

13. Expand the Altair HyperWorks book by double clicking it, or selecting it and clicking Open.

14. Open the HyperMesh book, and expand some of the available books to review their content.

15. Bring up any topic by double clicking it in the tree structure.

When you need to find specific information, you can look for it in the table of content using the

Contents tab, or have the help system look for it by using the Find engine.

16. Click Find to bring up the Help Topics dialog with the Find tab.

17. Click Options… to review the search engine options, and click OK to close the Find Options

dialog.

18. Experiment with the Find tab by typing some words and looking at the results.

The result is a list of topics matching words you entered and the criteria you set in the Options.

You can then review a topic of interest from the list by double clicking it, or selecting it and

clicking Display. To review another result topic, simply click Find again as the same list of topics

for the criteria specified will still be available.

19. Close the help.

Notes If the help button is clicked from a main menu page, the help system will start at the

topmost book level of HyperWorks help, and you can navigate your way through the help

system using the Help Topics dialog.

The help system can be started outside of HyperMesh from the Start menu in Windos

(Start/Products/HyperWorks <version>/Altair HyperWorks Help), or by

typing winhlp at the UNIX command line from within the

<install_directory>/scripts directory.

File input and output

In this section, you use the files panel to retrieve a HyperMesh database. The files panel is primarily

used for all the input and output of files, and setting up solver templates.

1. From any page, select the files panel (leftmost column).

2. Select the hm file sub-panel by clicking the corresponding radio button.

This sub-panel is used to save and retrieve HyperMesh binary files, which contain all of the

information in the HyperMesh database, including geometry and finite element model data. While

HyperMesh has no specific file extension requirements, the typical extension is .hm. Only one

HyperMesh binary database can be opened with this sub-panel per session.

The four green buttons on the right side of the panel are used to save or retrieve the HyperMesh

database. The save as… and retrieve… launch a windows style file browser to allow you to

Altair Engineering HyperMesh 7.0 Tutorials - HM-1000

locate the desired file on your system. The save and retrieve buttons (without the …) simply

read or write to the filename listed in the file: field.

3. Click retrieve….

An Open File… dialog appears. The starting point is your current working directory, and the filter

for Files of types… is set to HyperMesh binary files (*.hm*).

Open files dialog

4. Change directories to the <install_directory>/tutorials/hm directory.

If you do not know the location of the <install_directory> installation directory, see Finding

the Installation Directory <install_directory>, or contact your systems administrator.

5. Select the file bumper.hm and click Open.

You can also double-click the file name to close the file dialog and read the file into Hypermesh.

The bumper model displays in the graphics area. Notice the file: field contains the path and file

name just loaded into HyperMesh. The path and file name also display in the title bar at the top of

the HyperMesh window.

If at any time you would like to revert to the original model (discarding any changes you may have

made), click the retrieve button (the file browser will not open). To save any changes you have

made, (overwriting the original file) click the save button. If you would like to save your changes

with a different file name or location, use the save as… button to open the file browser, or update

the path and name in the file: field and click save.

6. Look at the other sub-panels in the files panel by clicking their corresponding radio buttons:

import HyperMesh can import HyperMesh binary files (HM MODEL), geometry files

(GEOM), finite element information (FE), weld location and connection data (WELD).

Simply select first the type of data to import, and then the appropriate import

translator.

When data is imported into HyperMesh, it is appended to the current session

database. An import translator reads data imported and converts the native file

format into one HyperMesh understands. Import translators are included for many

finite element solver input formats, as well as many common geometry formats.

export The export functionality is used to convert information in a HyperMesh database into

a solver formatted input deck, to export geometry as IGES data, or to export weld

information. In order to write data as a solver input deck, HyperMesh uses feoutput

templates to define the output format. The feoutput templates also define the card

images of the different entities. (See Interfacing with solvers)

Tip: Load the feoutput template prior to creating any finite element entities, like

materials, elements or loads. In this way, the solver specific entity type and required

properties can be defined most efficiently as the model is created.

command The command subpanel allows you to execute a HyperMesh command file (a file

containing commands allowing you to automate or re-create HyperMesh sessions).

template The template sub-panel allows you to specify which solver template file you want to

load.

results From results, you can load HyperMesh results file obtained by translating (solver

panel or command prompt) solver result files.

Viewing the model using options from the permanent menu

The top half of the permanent menu contains view manipulation tools. The functions can be activated

either by clicking the button on the permanent menu, or by pressing the corresponding key on the

keyboard (for functions with a single letter on the button), or the four arrow keys.

Permanent menu

Zoom functions

The zoom functions allow you to scale the size of the model display in the

graphics area.

Try each of the five zoom functions on the bumper.hm model loaded in the

previous section.

Circle zoom function. When activated, move the mouse into the

graphics area, then click and hold the left mouse button. Circle the

part of the model you want to zoom in to, and upon releasing the

mouse button, the view will be adjusted.

Fit function. Fits the entire model to the graphics area.
