API

See the 2021.2 API Programmer’s Guide for the full list of new features and enhancements.

Enhancements

New Internal ID Management: From this version onwards, HyperMesh synchronises the internal IDs with solver IDs whenever possible, the exception being models with duplicate solver IDs (allowed in Nastran, LS-DYNA, OptiStruct and Radioss solver interfaces).; This means for models without duplicate IDs no extra measures need to be taken for mapping internal IDs to solver IDs and vice-versa for the purpose of passing the correct entity identifiers to the Tcl API commands. Note that hm_createmark, hm_getmark, or hm_getvalue commands operate with internal IDs rather than solver IDs. The same applies when querying entity IDs in Matrix Browser.
Assigning Parameters: Parameters can be now assigned on entity attributes using *setvalue command, for example, *setvalue mats id=1 Rho={parameter parameter_name}. Similarly, the parameter can be unassigned by providing an empty name string, for example *setvalue mats id=1 Rho={parameter "" }. Upon unassigning the parameter, the entity attribute will automatically adopt the same value as the one assigned via the parameter.

Browsers

New Features

Add metadata to entities

The Add Metadata dialog facilitates adding metadata to all the types of entities. The added metadata is saved to *.hm file.

The Add Metadata dialog can be accessed by right-clicking on an entity/folder in a browser or by right-clicking on the Metadata category in the Entity Editor.

Adding metadata as a browser column is supported for entity views for bulk reviewing or editing. An existing metadata can also be applied to other entities of the same type from the browser column.

Demo Browser

New browser available in HyperMesh view menu. It allows you to quickly open files in the Demos/hm/ folder in the installation by double-clicking or right-clicking and selecting open.

Entity Defaults

Entity attribute default settings is a new mechanism that allows control of entities and the Entity Editor. It can be configured in the following ways:

Entity attributes can be flagged as mandatory. If set, it is shown in the Entity Editor by the red triangle in the field. As an example, thickness could be mandatory.
Default attribute values can be defined. Once defined, creating an entity will have those values applied. For example, the default value for thickness may be set to 5.0.
Entity attribute fields can be removed from display. For example, NSM can be removed from the Entity Editor display, preventing access

The settings are stored in an EntityDefaults.xml file and can be applied at the individual user, team, or enterprise level.

Enhancements

Element subcategories in Model Browser: Subcategories for elements, based on solver keyword, are now shown in the Model Browser for OptiStruct, Nastran, and Abaqus interfaces.

Figure 3.
Solver keyword list for Create context menu: In OptiStrcut and Nastran interfaces, the solver keyword list under the Create menu is redesigned to show the most used keywords at the top and the rest under the More category.

Figure 4.
Attribute columns for Systems and Vectors: Flat entity views are now supported for Systems and Vectors that facilitate adding any entity attribute in the browser column for bulk review and editing.
Create Part and Subsystems from Model Browser: Part and Subsystem entities can now be created from the Model browser.
Embedded EE expand/collapse state: The expanded/collapsed state of embedded EE for referenced entities is now retained across different selection of same entity type.
Parts from includes/subsystems: Double-click the Parts folder under an include or subsystem to show a filtered Part Browser with just the selected parts.
Expand/collapsed state on filtering: The expanded/collapsed state of a parent entity in the browser is now retained when a parent entity is a match for the filtering operation.
Referenced entity check on Organize: The new Organize option with referenced entity check is now supported in OptiStruct, Nastran, and Abaqus interfaces.
Show/Hide/Delete attached options added to Preferences: The Show/Hide/Delete attached options can now be changed from the Preferences dialog.
Beam Section creation from Beam Section Collectors view: Beam Sections can now be created in the select Beam Section collector from Beam Section Collectors view.
Include file creation from Include view: Under Includes view, Include File is set as the first option under Create menu for quick creation.

Composites

New Features

Ply Types: Ply product type support has been added for Unidirectional, Weave (homogenized and unidirectional models), Core, and Filament Wound.; Based on the type selection, product specific details are managed by a drape table. For example, a single wound ply type can hold a spatially varying number tows, where each tow's thickness and orientation can vary.; Visualization and laminate realization are supported for all ply types.
Composite Stress Toolbox: Analysis entity stores entities (materials, plies, laminate, or zones) along with all other analysis specific settings. This allows easy setup of and access to classic laminate theory calculations including engineering constants, strength, load response, and first ply failure.; Composite plate loads (Forces and moments, strains and curvatures, and homogenized stresses) can be created and assigned to load response/first ply failure analyses.

Enhancements

General: Kinematic draping support added for Abaqus, Ansys, LS-DYNA, and Radioss profiles.; MCSID visualization support in Nastran profile (accessed in Orientation Review tool).
Composite Stress Toolbox: First ply failure methods can be created in composite browser and assigned to laminate strength and load response/first ply failure analyses.; Laminate load response and first ply failure analysis provide insight to laminate load state, material system stresses and strains, invariant and principal results, as well as ply level first ply failure results.

Figure 6.

Known Issues

Auto Pitch/Auto Point new tool to map the auto pitch tools to the new interface.

General Improvements

Connectors will no longer realise to a Realize component when No/Skip Post has been set to on. Components are created following a standard naming convention to ensure consistency.
Connectors will put the Property and Material (where the material is defined on the component) in the Component realisation name when using No/Skip Post.
hm_createmark can now be used to select Connectors by Subsystem.
HiLock Fastener has been adjusted to allow for PCOMPG or PCOMPP as properties on the component links.
HM Metadata is written out in the Connector XML when exporting.
The control binary file can now be auto-loaded by defining the control file in the Connectors area of the Preferences dialog.

Resolved Issues

Subsystem connectors no longer incorrectly absorb to the wrong include.

Design Explorer

New Features

Measure Response: The measure response allows you to create responses from various useful measurements of interest: distance between, position, relative displacement, relative angle, and angle between. In each case, you will select the appropriate number of nodes to capture the measurement, and the measurement will be evaluated and reported in each run of the exploration.

Design Space

New Features

Adhesives design space workflow has been added. Adhesive tool automatically identifies flange locations from the selected entities. It also creates a Tie based contact between Adhesives design space (voxels) and the structural elements nearby. It does not add any additional stiffness as it does not create any contact between structural parts. Figure 7 used to improve stiffness, but the adhesive length is not optimized.

Figure 7. Sample Automotive Model with Structural Adhesives

Figure 8. Evolution of Structural Adhesives Before and After Optimization
Tie connect workflow has been added that generates contacts only between the selected design space and nearby structural elements.

General

New Features

Toolbelt

The Toolbelt, a feature known from Altair Inspire, has been introduced to HyperWorks. You can quickly access frequently used tools by using the preset defaults or by defining a personalized Toolbelt by dragging and dropping. Modified definitions can be exported to an .xml file and shared with others.

To launch the Toolbelt, hold the modifier keys (ALT, ALT + CTRL, ALT + SHIFT, ALT + CTRL + SHIFT), right-click, and drag. To define your own Toolbelt, use the configuration menu shown in Quick or Complete Mode in the lower left corner of the circle of tools.

Selection search interface for Entity Editor

A new typing interface with live search suggestions is now available to select individual entities in the Entity Editor. To select by entering names or IDs, use the button, or press . or Ctrl > Spacebar. While typing, the selection search function provides live suggestions of names and IDs that contain the typed search terms. If the model contains more partial matches than listed in the suggestions list (configurable in Preferences), you can also click Browse More, or press Ctrl > Enter, to browse and select from the full partial match list.

Advanced Selection Operators: Add, Remove, Intersect

It is now possible to choose whether extended selections in the Advanced Selection dialog will be added to, removed from, or intersected with any current selection. The operations can be immediately chained without leaving the dialog, so it is possible to perform more complex actions. For example, adding elements on a face and then removing elements from hole edges:

Cascaded advanced selections

The

button is now also available for selection methods inside the Advanced Selection dialog, allowing to perform multi-level extended selections. For example, selecting Elements, By Property, and By Include:

Renumber tool

A new Renumbering tool is now available on the Assembly ribbon. In addition to a modern UI and workflow, the new tool provides enhanced feedback and also offers the ability to renumber ordered lists of nodes and elements.

Spatial ID Manager

A new Spatial Renumbering tool is now available on the Assembly ribbon. It allows you to renumber nodes/elements using the system axis:

Pure spatial sorting with constant increment of ID.
Following rectangular grid schema with different increment per direction (same as the legacy tool).
Using adjacent elements: You no longer need to select the direct adjacent element to define direction (internal path search is performed).

Enhancements

Selection

Set Segment contents selector in Entity Editor has been migrated from the legacy panels to a new Entity Selector that allows appending and deselecting the segments’ base elements directly.

Use standard selection controls to append or deselect Elements, Facets, Faces, or Edges where the Segments are defined.
Click to reverse or align Segment directions using the Adjust Directions dialog. The Reverse function flips all or some Segment directions simultaneously. The Align function is only available for Segments defined on shell elements.
When selecting 3D elements, Segments will be added to their outside faces only, based on the current display state.
While selecting Set Segment contents, you can freely switch between supported selection types (for example: Elements, Facets, Faces) and the current selections will be converted accordingly.
Consult the product documentation for additional restrictions and considerations for this special selector.

New advanced selection methods:

Connectors > By State (Realized, Unrealized, Failer)
FE Edges > By Path

New configurable quick advanced selection (Alt > Select) support for Tag entity.

New snap types:

Element centroid
Element edges

Preferences

HyperWorks Preferences are available in the Preferences dialog where you can edit preferences for all loaded clients in the current session in one place.

Some HyperMesh specific pages such as Application, Graphics, and Browsers have been moved to the HyperMesh category in the Preferences dialog. New additions include the Capture page for image capture and the Export page for H3D export preferences.

The default for swipe to exit has been changed to off. To re-enable go to Preferences > Appearance > Context Menu > Swipe to exit.

The default for plotting entity graphics has been changed to off. To view Plot entities in the graphics window, go to Preferences > Appearance > Plots > Plot entity graphics.

Nearby

Many more entity types are now supported for finding nearby the current selection:

Model files removed from installation package

To reduce the footprint size, the following tutorial model and demo model files are no longer included in the local installation. You can now find zipped tutorial model files and demo model files on Altair One via the Altair Community, Altair Marketplace, and Altair Connect sites. Altair recommends that you create an Altair One account and use it as your primary portal to access product documentation, a Knowledge Base, and customer support.

Resolved Issues

Issues related to pinning HyperWorks to the taskbar or invoking HyperWorks from a pin in the taskbar in Windows have been resolved. This fix applies to all HyperWorks applications that have start menu shortcuts.
An issue affecting the display and refresh of the GUI while using a remote display manager in next-generation applications including HW, Inspire, and SimLab, has been fixed.
Performing quick advanced selection (Alt + Select) of Elements > By Path with the Fill Path loops option enabled is now possible. The enclosed loop area will be selected upon releasing the Alt key, without the need to press MMB (since Alt + MMB is a differently assigned shortcut key).
Fixed an issue where currently selected Parts were not being automatically inherited when entering the Move tool or other tools supporting Part selection.
Fixed an issue where the session crashed while hovering over the undo list in the Edit menu.

Known Issues

If you have more than one defined keyboard language, pressing ALT + SHIFT to open the toolbelt also switches the language. The shortcuts for switching keyboards can be modified in the Windows settings for Languages.
In HyperWorks, if you start HyperView without cleaning your settings first and then switch to HyperMesh, the solver profile is not loaded properly, though there is a checkmark by it in the Solver Interface menu. This results in the loaded/available element types and full entity properties not being visible.
Workaround: Select the solver interface from the Solver Interface menu (File → Solver Interface), even if it already appears selected, to manually load the profile.

Geometry

New Features

Sketch

HyperWorks 2021.2 features a new sketching interface and a number of new sketching tools. You can create sketches, add dimensions, convert driving dimensions to reference dimensions, and add constraints. Highlights include:

New sketch tools: Points/Lines, Rectangles, Circles, Polygons, Ellipses, Arcs, Splines, Dimension, Trim/Break, Extend, Fillet, Offset, Mirror, Project, and Intersect.
Constraints: A complete set of sketching constraints are now provided including fixed, vertical, horizontal, midpoint, coincident, colinear, tangent, perpendicular, parallel, concentric, and equal.
Dimensions, relations, and variables: All geometry can now be dimensioned, and variables or relations can be used in the dimension definition.

Figure 18.
Extract tool added to the Geometry ribbon to convert sketches to geometric lines or surfaces.

Cut Hole

New tool on the Geometry ribbon to create holes in geometry/2D mesh using predefined shapes as:

Slots
Circles
Rectangles
Curved rectangles or curved slots
Polylines

The tool includes a mesh rebuild feature to generate washers around holes.

Enhancements

Parasolid option added to detect and remove fillets
Added auto-imprinting options for nodes and geometry creation tools
Imprint tool now supports node imprinting on lines
Splitting a line with multiple lines added
Defeature holes tool shows count of number of holes detected

Resolved Issues

Fixed issues with detection of thin solids for models with T-connected edges for midsurface extraction
Miscellaneous issues related to ruled, split and defeature hole tools fixed

Matrix Browser

New Features

New Access Point

The Matrix Browser can be now accessed from the Query section of the Post ribbon. Note that Matrix is no longer accessible from the Aerospace pull-down menu – the entire Results section has been migrated to the Post ribbon.

Results Query

The result data coming from the Results entity in HyperMesh can now be queried via the Matrix Browser. A new item – "results" – has been added at the end of the list of available data names for elements and nodes.

New Settings Options

Two new options have been added to the Settings:

Control of numeric format of the queried result values
Display of subcase and simulation name in the column header

Enhancements

Solver IDs vs Internal IDs: The Matrix Browser lists the internal IDs in the entity query column. Historically, this has posed challenges when exporting the data and matching it with solver data because the internal and solver ID were often different. Thanks to the new internal ID management, HyperMesh now synchronizes the internal IDs with solver IDs whenever possible, the exception being models with duplicate solver IDs (allowed in Nastran, LS-DYNA, OptiStruct, and Radioss solver interfaces). Also, the solver ID is now available across all the entities as a core data name, and it can be directly queried in the Matrix Browser.
Removed Deprecated Data Source: The MatDB data source has been removed from the selection list.

Known Issues

The results query is not yet supported by the macro recording. This requirement will be addressed in the future release.

Meshing

2D Meshing

New Features

Associativity to geometry: Always maintain original node associativity to geometry like vertices/edges/surfaces/solids. Most geometry, meshing, and mesh editing tools, with a few exceptions, are instrumented to use new associativity. Mesh will no longer lose geometry associativity on editing.
Edit Elements: Added Origin tool to review associated nodes moved away from the geometry and move them back to their initial positions.
Doubler: Doubler workflow has been added under 2D → Mesh to create a part that provides localized performance benefits for multiple design attributes such as NVH, Safety, and so on. The workflow creates the physical part at the desired location, applies thickness and material properties, and also connects the part to the surrounding structure.
Edge layer mesh controls: Edge layer mesh controls added to generate 2D BL layers.

Enhancements

General 2D mesh and Panel Mesh

Added “Element organization” and “Treatment to connected mesh” options at local context level.
Enhanced Face Edit tool workflow and added new mapping method for Map as Triangle (Tria centre and Tria corner).
Extended support for number of layers upon Redo connectivity.

Edit Elements

Replicate tool enhanced to Auto detect FE stitch shared edges with 2d-3d elements.
Edit Density tool supports element re-mesh with specified number of layers.
Box trim UI and workflow enhanced.
Section Property (in Mesh 1D Group)

- New feature to consolidate the beamsections resulting from multiple cuts using a tolerance on calculated moments of inertia. This reduces a lot the number of section created.
- New option to translate beams to the actual shear center location instead of applying offset
1D Beam Review
- New flag to review offset values as tooltip while hovering mouse on element
- New item in legend to display orientation vector along with x,y,z elemental system
Bulkhead
- Within the bulkhead workflow, it is now possible to apply the material to the newly created part.

Resolved Issues

Fixed miscellaneous issues in the Refine tool and addressed inconsistencies.
Midmesh Align distorting mesh resolved.
Fixed topology revision issues related to remeshing of geometry after unstitching of T-connections

Solid Meshing

New Features

Added “Thin Solid” tool in Mesh ribbon to generate Hexa-Penta mesh on thin solids like sheet metal solids and electronic components having relatively smaller thickness.

Resolved Issues

Resolved “Growth Rate” issue related to Tetra mesh.
Solid Map tool now allows selection of partial mapped solids upon clicking on “Find” option.
TetraMesh panel bug (application hang) pertaining to the Abaqus profile fixed.

Model Build

New Features

PDM Live connections: HyperMesh can interact directly with PDM systems via the Part Browser. It can download/upload data to PDM systems from within Part Browser on Demand. This makes the HyperMesh-PDM integration more robust and very intuitive, helping the CAE world to work seamlessly with the PDM world.

Enhancements

Identifying and linking symmetric parts as instances is now supported.
Support for parts and instances is added to the Mirror tool. Mirroring a part with "Keep original" will create a new mirrored instance of the selected parts.
When loading part representations, there is now a progress bar so you know how far through the load process you are.

Resolves Issues

When a component is moved from one part to another, it is no longer automatically transformed by the new part's position; it is instead left in the same position in space.
After going to a New Model in a HyperWorks session, the Model subsystem is no longer exposed.
The subsystem icon will now update when parts or components are shown, hidden, or isolated so you can check which subsystems are displayed.
Since connectors are listed directly in the Subsystem Browser, the Connector section from the Subsystem Entity Editor has been removed.
Creation of multiple subsystems from Includes now creates subsystems in the same order as the Includes.
The Library and Export Deck options were available in the Subsystem Browser only in HyperWorks. They are now available in HyperMesh as well

Model Verification

New Features

Quick Comparison works for user-selected Parts directly from HyperWorks graphics.

Figure 20.

BOM Comparison displays 31% Match if Part Revision is mismatching but Parts Name/Number/PID is matching.
Merge Comparison Excel reports to single/few based on user input. For every result ranges, MergeExcel.xlsm is created.
Skip calculating Oriented BBox from Cad or FE if component has zero nodes/surfaces.
New Part pair Revision filters are added (Same-Pid-Only+Revision....).
BBOX creation is improved to exclude scattered parts while calculating and distributing parts for the parallel processing.
Connection Holes-Mismatch and Holes-Pair-Mismatch checks are parallelized for the reports.
File size check is added before attaching the common representation to a Part (applicable to offset function).
Part Match function the #solids count depends on Parameter.
Connection Check and Report, Parallel session starts after 10min of delay to accommodate load balance.
Delete Connection/Unwanted filter groups from configuration file at once.

Figure 22.

Relocation of Parameters

All color related parameters for the comparison function is moved under compareunified/report/color.
BOM Comparison related parameters are moved compareunified/Bom comparison
String Range parameter for controllling Part Name, Number, Assembly names are moved under general/tool.

Resolved Issues

After an MVD run, configuration from mvd temp folder was active.
Connection Check, hm_getmark errors displayed on huge models.
Part Match, renaming Part Set name considers PartName in addition to PartNumber.
Mixed Import, will work directly from Intersection GUI.
BOM Comparison, Part color is being displayed for unmatched range when 3 levels threshold value is chosen for CAD-CAD compare.
Representation file type gets changed from FEM to CAD file when cadtofeapproach is executed using browser selection method for the 2nd time.
Module Pair Ignorable filter must accept attribute PartName in addition to PartNumber.
Configuration, Search option not working if the Tree is in a collapsed state.

Morphing

New Features

Morph Normal to Mesh: In the Free and Proximity morphing tools, it is now possible to toggle the Move tool mode between translating & rotating (default), or offsetting normal to mesh. Click in the Move tool microdialog to replace the standard Move tool with a single normal offset arrow. While in this mode, drag or click on the arrow to type a normal offset value to move the nodes. Optionally, use the microdialog buttons to review and edit the normals calculation options and area. This mode is not available for nodes connected to 3D elements.

Figure 23.
Morph Remesh and Rebuild Options: New options have been added to the Free, Proximity, and Volume morphing tools to monitor specified element quality criteria during morphing and automatically offer to remesh the affected elements using HyperMesh's rebuild or remesh technologies. The morph remesh microdialog appears when the specified remesh conditions are met, and allows reviewing and editing of the remesh parameters and area of effect. It is also possible to selectively skip any triggered remesh condition. When remeshing a morphed mesh using these tools, the morphing vectors are also automatically mapped to the new mesh, so it is still possible to save a morph shape from the morphed and remeshed area.

Figure 24.

Enhancements

Undo All Morphs

A new satellite icon has been added to the Shapes tool to provide quicker access to the Undo All Morphs function. Use this button to immediately undo any currently applied morphs in the current session. As a reminder, you can also execute the Undo All Morphs and Redo All Morphs functions while inside any morphing tool by using the keyboard shortcuts Shift + Ctrl + Z and Shift + Ctrl + Y, respectively.

Undo Shapes as Morph Input

It is now possible to select existing morph Shapes as input to create new morphs using the Free and Proximity morphing tools. When selecting a Shape, the Move tool is replaced by a shape magnitude arrow that can be used to move the nodes freely along their Shape. The magnitude is in the form of a multiplying factor with respect to the selected shape.

Other enhancements

Changed the default values for the 1D/connector automatic clustering parameters in the global section of the morph options. The new defaults represent less constrained morphing conditions that can speed up many morphing scenarios significantly. Models already created and saved using the previous default values will not be affected, as these settings are saved with the model. The new default values for these options are:
- Connector/cluster/eq morphing = use doms/mvols
- Stretch mesh around clusters = off
Morph volumes are now temporarily hidden from view while animating morph shapes.

Resolved Issues

Fixed a performance issue in Proximity morphing where using the "Morph only connected nodes" option could cause additional delays in some models.
Fixed an issue introduced in version 2021.1 where the automatic Morph Area detection in the Free morphing tool was sometimes propagating beyond the expected connected faces.
Fixed an issue where microdialogs could post in an overlapped manner in some morphing tools.

Post

Highlights

A brand new set of tools and workflows has been released in HyperWorks (HM) on the Post ribbon to allow direct integration of native results readers into HyperMesh and perform results visualization on the model via:

Contour plot
Vector plot
Tensor plot
Deformation plot

The new workflows are available for the following solver profiles:

OptiStruct
Nastran
Abaqus (Plot Workflow as Beta)
ANSYS (Plot Workflow as Beta)

For all other solver profiles, the Post ribbon hosts a configuration which points to older panels for Contour, Vector, Deformed, and Transient workflows, which rely on *.res file availability.

Plotting

New Features

Importing Results

Results can be imported directly into HyperMesh using File > Import > Results.

Currently supported solver related extensions are:

OptiStruct (h3d, op2, hdf5, h5)
Nastran (xdb, op2, hdf5, h5)
Abaqus (odb)
Ansys (rst)

Batch Import:

Load combination file (*.csv) can be used to import files/resources and their relevant subcase and simulation steps to generate a result entity.

In addition, you can create definitions of Derived Load Cases (DLC) in form of:

Linear Combination (Superposition)
Envelopes

Results Browser

After importing the results, you are brought directly to the Post ribbon with the Results Browser open. The browser can always be re-opened by clicking the Results tool on the Post ribbon.

Results Hierarchy

Each imported file is shown under the main result root as a resource.

Each load case (and simulation step) is listed under the pertinent resource it belongs to.

New files can be added using the Import/Add Results satellite icon.

Subcase/Simulation Status Bar

The current Subcase/Simulation can be set by:

Double-clicking the subcase/simulation entity
Right-clicking on an entity and selecting Make Current.
By changing the active collector on the status bar at the bottom of the application.

Plotting Tools

Each plot workflow relies on a plot control entity and can be accessed either via the Plot or Create options.

When there's no plot control of any of configuration in the database, the Plot option creates such an entity.

Each plot control workflow on the ribbon exposes a guide bar with the following:

Available plot control to be selected (from that specific configuration)
Icon to expose a floating Entity Editor (EE) to set the data to be displayed and the relevant options
Entity selector
Plot execution (without exiting the tool)
Plot execution (exiting the tool)
Clear plot
Exit tool

Data types available for each plot control are “children” of the current subcase/simulation selected.

Any plot control can be activated (once available) from the Results Browser by simply clicking its icon. Only one plot control per configuration can be activated/displayed in the graphics.

Once out of the tool, the EE is shown in relevant property area in the Results Browser.

The context menu in the Results Browser (blank area) gives access to the Clear Plot option, which cleans the graphics and turns off the display of all plotted controls.

Once any plot control is on/active, each modification of the EE properties is automatically committed and the graphics are automatically updated. This occurs as well by changing/switching to any other subcase/simulation step.

Contour

Contour plots visualize result data by coloring entities by value, allowing for easy identification of maximums and minimums throughout the model. Contour plots can be created using any scalar data, including components or invariants of vector or tensor results (e.g. vonMises stress, displacement magnitude).

Averaging: The standard (simple) averaging methodology supported is equivalent to the HyperView advanced one. That means that tensor/vector invariants are evaluated/extracted from the full averaged tensor quantity after each component has been averaged with respect to a given system (Global or User Defined).
Currently the averaging methods is across part boundaries.
Iso Plot: Due to current graphics limitation, the elements removed from Iso thru the slider in the legend are still “displayed” for the database and can be selected either via idle mode or via API.
3D Visualization: 3D visualization of shells and 1D elements is supported when a contour is applied only when the data types are elemental bound and with single association. Support of nodal/corner bound values is a work in progress.

Vector

Vector plots are useful to draw arrows such that the direction in which the arrow points is the direction of the vector and the length of the arrow is its magnitude. Individual vector components, shear, and complete resultants can be plotted for vector-based results. (eg, X, Y, Z, Resultant).

Visualization on Deformed: See Deformation [Tensor and Vector on Deformed]

Tensor

Tensor plots are useful to analyze the overall contribution of quantities like Stress and Strain on the relevant entities.

Currently, only component view is supported (Principal View is a work in progress).

Visualization on Deformed: See Deformation [Tensor and Vector on Deformed]

Deformation

The Deformed tool is used to specify parameters for deformation display. This displays the original structure and the deformed shape to see the total amount of movement or view the deformed shape by itself.

Scaling factor currently supported is limited to uniform one.

Selection: When a deformation plot is active, window selection is disabled.
Tensor and Vector on Deformed: Vector and tensor are currently always shown in undeformed shape. If deformation is on and either a tensor or vector plot are displayed, an undeformed shape (with default component color mode) is displayed and relevant quantities are drawn using it as reference.

Figure 27.

Legend

Contour, Vector, and Tensor plots display a dedicated legend. Each result legend can be currently moved anywhere in the graphics area, but its position is restored any time a display operation is performed.

The legend has an associated right-click context menu.

Safety Tools

New Features

Seat Foam Deformer: This new feature allows you to perform the seat foam deformation process directly in HyperMesh. Compared to the existing seat deformer using the pre-simulation approach, the seat foam deformer enables you to quickly get high quality results of the new seat foam shape, removing intersections with the dummy.; This new feature is available in the LS-DYNA and Radioss interfaces.
Dummy pre-simulation: A new feature in the dummy pre-simulation tool now allows you to directly select the initial dummy file, which is then automatically used for the simulation process. HyperWorks only exports an include file containing the load case information and a master file referring to the dummy and load case includes. This leads to an improvement of the performances of the tool, reducing the time for the export of the simulation deck.
Combined seat and dummy pre-simulation: This new feature, accessible from the Dummy pre-simulation GUI, enables you to set a pre-simulation run to perform the seat deformation and the dummy deformation in a single stage. This improves the occupant safety model set-up process by reducing the simulation time requested for the seat and dummy pre-simulation.; This new feature is available in the LS-DYNA and Radioss interfaces.

Enhancements

Mechanism tool: The joints attributes are now fully editable after the joint creation process, allowing an easy update of the joints. Delete and re-create the joint is no longer requested.
Seatbelt system performances: The performances of the seatbelt system tool are drastically improved, especially when modifications operations on the belt are applied. For example: interactive modification, belt update on dummy & seat motion, mesh size, or mesh type change...
Pedestrian tool: The marking of impact locations on outer surfaces is improved by considering openings, for example on the hood.

Resolved Issues

Reading of the Radioss native H3D file to update airbag, dummy, or seat with simulation results, is now working.
