HyperWorks Desktop Introduction

Getting Started - Running HyperWorks Desktop

WINDOWS

1) From the Start Menu, select All Programs > Altair HyperWorks (version).

2) Select the the application shortcut to run

HyperGraph - Starts HyperWorks Desktop with the HyperGraph 2D client loaded.

HyperMesh Desktop - Starts HyperWorks Desktop

HyperMesh - Starts HyperMesh standalone.

HyperView - Starts HyperWorks Desktop with the HyperView client loaded.

MotionView - Starts HyperWorks Desktop with the MotionView client loaded.

UNIX and LINUX:

1) Launch the system terminal and cd to the directory from which the HyperWorks Desktop

application should be run.

2) At the prompt, enter the full path of the HyperWorks Desktop application start script.

hg - Starts HyperWorks Desktop with the HyperGraph 2D client loaded.

hm - Starts HyperMesh standalone.

hmdesktop - Starts HyperWorks Desktop with the HyperMesh client loaded.

hv - Starts HyperWorks Desktop with the HyperView client loaded.

hw - Starts HyperWorks Desktop with the default client loaded.

mview - Starts HyperWorks Desktop with the MotionView client loaded. 11


HyperMesh Desktop Introduction

Getting Started - The Start-In Directory

The Start-In Directory or Working Directory is the location from which the

HyperWorks Desktop application is launched.

This directory ("current working directory) defines where certain settings and

configuration files are written by default; file browser will also use this directory as

its default location for browsing for files.

This directory can be changed, thereby changing the location where these files are

written to or read from. This has the benefit of allowing different settings to be

stored in different directories to give control over the HyperWorks Desktop

environment for different projects or use cases.

Changing the Start-in Directory

On Windows, can be changed by editing the "Start in" field on the application

executable or its shortcut.

On Linux, the start-in directory is defined by the directory from which the user runs

the application startup script.

12


HyperMesh Desktop Introduction

Getting Started - Online Help

HyperWorks Desktop offers comprehensive documentation in the online help.

The Help can be accessed through the menu bar or the use of the h , keyboard

(help documentation is intelligent, opening in the section representing the panel

that the user is actively in)

Help also contains detailed tutorials on many advanced functions.

Questions & Answers


Contour Plots

Two different ways to create Contour Plots

1) Contour panel:

Contour icon on the Results toolbar

select Results > Plot > Contour from the menu bar

54


Contour Plots

1) Contour Panel

Result type: select the result type and component to be contoured.

Tensors (t), vectors (v), and scalar (s)

Layers (if applicable): display a contour for a specified element layer

Use corner data (if applicable): when selected, HyperView displays color bands by

interpolating available corner results within each element. This allows for a

discontinuity of the result distribution across element boundaries to be seen.

This option is only active when corner data is available in the results file

55


Contour Plots

1) Contour Panel

56

Selection: pick entities in graphics area or using the Elements, Components, or

Assemblies input collector. If no selection is made, the contour will be applied to

the displayed entities

Resolved in: select the result coordinate system to be used to contour the results.

Global - transforms to the global system

Elemental - transforms results to the element coordinate system

Analysis - displays the vector and tensor results as they are output from the

solver

User - available when the results file contains a user-defined coordinate system

Use tracking system - If you activate this option, the results will be transformed

and resolved in the activated tracking system


Contour Plots

1) Contour Panel

57

Averaging method Nodal averaging of elemental results


Contour Plots

1) Contour Panel

58

Averaging method (None, Simple, Advanced, Difference)

None no averaging done Simple - tensor and vector components are extracted and the invariants

are computed prior to averaging

Advanced - tensor (or vector) results are transformed into a consistent

system and then each component is averaged separately to obtain an

average tensor (or vector)

Difference - difference between the maximum and minimum corner

results at a node


Contour Plots

1) Contour Panel

59

Averaging method Variation (optional): used to control the nodal averaging calculation

Off - the average results are calculated for all nodes

On - the average results are calculated for only some nodes, depending on the

variation (%) you have defined


Contour Plots

1) Contour Panel

60

Envelope trace plot option allows you to trace the results from envelope

subcases or simulations

Complex results - Complex results are supported in HyperView and can be

contoured using the Contour panel.

They can also be animated using the Modal Animation Mode, . After

switching the animation mode to modal, an additional option appears in the

Contour panel which allows the users to set the Complex filter.

The Complex filter selections available are:

mag*cos(t-phase) The response with varying angle or t (in degrees) mag Magnitude (r) of the complex result phase Phase () of the complex number real Real part (x) of the complex number imaginary Imaginary part (y) of the complex number Complex Results are shown in the Result type list with a (c) appended to the result name.



131

Complex results - Complex results are supported in HyperView and can be

contoured using the Contour panel.

To view contour of complex result at certain angle, use Animation Controls and set the

Current angle

Also in the Animation Controls panel, the Angular Increment can also be set. This is used

when animating the model (see image above). To start the animation, click on the

Start/Pause Animation button .



132

Contour vs. Angle - Using the Measure panel, the contour value can be

plotted vs. angle. 1. Set the animation mode to the Modal Animation Mode, .

2. Use the Contour panel to create a contour plot of the appropriate data.



133

Contour vs. Angle (continue .) 3. Add a measure group with the type set to Elemental/Nodal Contour.

Common post processing need is to take element based result and sum the values to find

the part based value

One typical result that this is done with is strain energy

Take strain energy values that are element based and use the Derived Results

Expression Builder to find the part (or component) based value

Same procedure could be applied to any result type that is element based that you would

like to find the part based value of

1) LOAD - The first step is to load the Advanced Result-Math Template into the

session. This is done in the Open Model panel ( ) and selecting the Result-Math

template to Advanced.

2) CONTOUR - The next step is to contour the model with the appropriate result type.

Again, in this example we are interested in summing strain energy values, so the strain

energy contour is applied:
