to the Connectors Ribbon. This is a direct mapping of the
Attachment workflows from the browser.
A new Attachment type is added to the Rigid Patch attachments.
This new type projects the attachment onto a plate. Figure 7.
Connector Browser
A new browser following the new paradigms from Model Browser.
The different connectors are now split into separate tabs. Figure 8.
Enhancements
Connector Group Logic
Used when dragging and dropping connectors to create a new
connector group. You are prompted to create multiple groups if
the connectors are scattered across many Subsystems. Each
connector group is then organized into a part, and the Part is
placed into the appropriate Subsystem.
If the organization is set to Automatic, and the Connector is
organized into a Subsystem different from the Subsystem the
Connector Group belongs to, the ownership of the Subsystem is
broken to ensure consistency.
Single Include for Subsystem Connectors
A single Subsystem is created for all the Subsystem connectors
to be organized into.
Organize connectors to current include
All the connectors are organized into the active include.
Seam connector Improvements

Design Explorer
New Features
Connectors as design variables and responses
Connector attributes can now be used as design variables and as a
response. Design variables can be created directly from connector
attributes such as pitch, tolerance, or diameter. In addition, a
connector’s connector control can become a design variable, allowing
different controls to be used for a given connector within an
exploration. Finally, a new connector response, the total number of
connectors, has been provided. This response can be used as an
optimization objective to minimize the number of connectors used.
Results compare contour
A new comparison contour has been added to the Results Explorer. You can
select and compare any two runs in an exploration. The comparison plots
the difference in design variables as a bar chart and also contours the
changes onto the model graphics, allowing for easy visualization of the
design variable changes.
Machine learning enhancements
Clustering
A new AI report has been added to the Scatter Plot tool in
the Results Explorer. You can now automatically group
exploration results into clusters, classifying based on
different criteria. This can be useful in cases where you
want to view or choose designs based on a certain
classification, such as deformation mode.
Field prediction performance
Field Prediction performance has been improved so predicted
results update more quickly.
Machine learning reports on demand
AI Reports can now be run on demand. Once an exploration has
been completed, the Field Prediction and Clustering reports
can be run, even if they were not originally selected when
the exploration was originally run.
Multi-objective optimization
Optimization explorations are no longer limited to a single objective.
Multiple objectives may now be enabled for an optimization. In addition,
an Optima option has been added to scatter plots in the Results Explorer
to allow for easier viewing of the optimal runs and the resulting Pareto
front.
Additional solver support
The Design Explorer is now supported in LS-DYNA and Abaqus solver
profiles. Note that to use the Design Explorer with Abaqus requires
additional configuration. Please contact your Altair account
representative for more information.
Nominal Run shown in exploration summary tables
The nominal or baseline run is now shown for reference in exploration
summary tables. Nominal run results can be easily accessed and viewed,
and the nominal run values are available for comparison to other
exploration runs.
General
New Features
Configurable Quick Advanced Selection (Alt)
The Quick Advanced Selection keyboard shortcut (Alt) is now
configurable across many different entity types. Previously it
was only possible to use this keyboard shortcut to quickly
select Elements > By Faces & Edges, and Nodes & Lines >
By Path. Now you can use the provided configuration dialog to
associate your preferred advanced selection method to any of the
supported entity types.
All Quick Advanced Selection methods support either appending or
deselecting by using the Ctrl or Shift modifiers,
respectively.
Access the Quick Advanced Selection configuration dialog from
either Preferences > Mouse Controls, or the Right-Click > Select
menu.
Figure 9.
Face/Edge Colors
The model color controls in the View Toolbar have been split into face
& edge colors. Face color is both mesh/geometry and edge color is
the edges of those entities. The icons update based on the current
colors being displayed in the graphics.
Geometry & Mesh Visualization
A new tool to control geometry and mesh visualization of selected
components has been added to the View Toolbar. It is available under the
Show/Hide drop-down or by pressing X.
Section Library
The automotive focused section library has been added to promote rapid
creation of full vehicle architecture concept models. The library
consists of various sections from the 2011 Honda Accord Body in White
(BiW) model*. The section library follows a unique BOM and
numbering scheme. Figure 10. Sections from Section Library Figure 11. BOM with Unique Numbering Scheme
Selection modifiers: Displayed, Reverse, Adjacent,
Attached, and so on
New Edge type options are available when using the Edges
selector, or the By Edge advanced selection method for Elements
or Nodes:
Edge types: All edges, free edges only, free loops
only
When selecting Nodes > By Path, an additional dropdown
menu allows including washer layers to free loops
selections.
Element Path Loops Area selection
Area selection using Element Path Loops is now faster and more robust.
It has also been enhanced to restrict the area selection to only
elements inside of a continuously connected enclosed area. To use this
feature, enter the By Path advanced selection dialog for Elements
(Spacebar, or Right-Click > Select > By Path), and enable the Fill Path
Loops option.
Resolved Issues
Issue with second order elements not being selected when using the Fill Path
Loops option inside the By Path advanced selection method for Elements has
been fixed.
Geometry
New Features
Features
The new Feature Manager allows detecting and managing geometric holes
(2D and 3D), fillets, flanges, and logos, as well as mesh holes and

localized performance benefits for multiple design attributes. For
example, NVH, Safety, and so forth. With minimal input, a bulkhead can
be created at a user-defined location along with their respective
parameters.
1D Mesh Property Update
A new tool has been added under 1D Mesh in HyperWorks called Section Property. It is exposed
for OptiStruct and Nastran solvers only. It enables you to update
properties with beamsections and materials as a result of a section cut
in a model. The source entities can either be surfaces, solids, or
elements (mix of shells and 3D solid elements).
1D elements are not yet supported as source for cut.
Multi materials are supported but not composite layered
shells.
Shells are inflated to represent actual shape.
Contact definition enables you to glue disconnected parts.
Shear Center and material weighted neutral axis are
calculated.
A generic beamsection is created along with an auto-calculated
material to account for correct stiffness terms.
Beam element is offset to account for element grid position with
respect to its shear center.
Limitation: section cut has a temp graphic in the tool but not
yet saved in a persistent way. Figure 14.
Box Trim
A new tool has been added to the Elements ribbon in HyperWorks.
With this new tool you have more control and flexibility, you
can add more than one graphical box, and those boxes can be
edited and moved interactively within the graphics area. Later,
those box faces (planes) are used for trimming of the complete
model, or the selected subset.
Graphical boxes can be quickly edited based on “Box Type” and
“Re-Oriented” with respect to global axis or with respect to
“best fit” method. This helps to quickly visualize and make
modifications before actual trimming.
Enhancements
BatchMesher/Rebuild
Support for rectangular/square, ellipse, slots, and mixed hole
shapes added for identification and various treatments (seeding,
washer creation, and removal).
Tria reduction and mesh flow improvements around free edges,
non-manifold edges, and washer regions.
Edit Elements Tool
Remap functionality added to Edit Elements tool. Remap a series
of nodes to a selected line list, the nodes become evenly
distributed across the line and you can select a set of nodes by
path and perform the Remap action.

move/optimize the node in the normal direction as shown
below. Figure 15.
In the case of hole/washer modify, the default preserve feature
is added and rebuild mesher is called for re-meshing.
The Split tool is enhanced to consider splitting underlying free
edges and 1d elements by default. In the case of fillets, middle
nodes would be projected to the parent surface.
Angle based correction method added under smooth function and
miscellaneous bug fixes done for Edit Elements
functionalities.
Thickness mapping tool is enhanced for Fixed interval method to
provide more control of thickness grouping.
Added an option to create mid-edge using discontinuous
guidelines in Midmesh Create Mid Edge tool.
Resolved Issues
Mesh flow issues corrected while splitting elements in midmesh using
node-to-node or node-to-shortest edge method.
Fixed bug related to Morph and Auto method in Replicate tool.
In the General 2D Mesh tool, corrected "Esc" behavior when using the Esc
key. Instead of directly closing the tool, now it takes you to "Create",
where you can select new surfaces/elements to redo meshing steps.
Reverse coloring allowed in HyperWorks
legend.
General bug fixes and robustness improvements.
Model Build
New Features
Instance Filter
Part Browser now has a predefined instance filter
that filters to show instances only. Based on selection, the filter
returns either all instances in the model, or siblings of the selected
instance. This predefined filter can be accessed from a list of queries
or manually applied. Figure 16.
Context Menus
Part Browser- and Subsystem Browser-specific context menu options are now
available by right-clicking in the graphics area when in idle.
