  • Ansys
  • LS-DYNA
  • Nastran


Figure 12.

Known Issues

Ply Stacking Performance on Large Models
If a large laminate is fully defined with a template property and plies which all have an assigned shape, performance while manipulating the stacking sequence by adding or removing plies or changing ply shapes may be slow. As a workaround, a ply with no assigned shape can be temporarily placed in the laminate and removed at the end of the stacking process.

Connectors

New Features

Auto Fastener Connector
An Auto Fastener tool has been added to pair holes and create connectors to join them.


Figure 13.

Enhancements

Line Connector Enhancements
Use the Imprint tool in the Connectors ribbon to imprint nodes as significant points to a line connector.
A Non Linear distribution option was added for significant points.
An option to remove significant points from connector was added.
A Skip Welding option was added to all realizations.
Connector Control Enhancements

An option was added to apply the element's direction as a vector during absorption.
An option was added to only display connectors/attachments linked to a specific part.

Design Explorer

New Features

Property Design Variables
A new type of design variable has been added where you can select elements or components in the model and allow their property assignment to become a variable within explorations. For example, you can choose a set of 1D elements and allow their section definition to be a variable.
Design Variable Link Equations
Design variable links have previously been limited to linking one or more variables to a main variable, ensuring that the linked variables’ value will be equal to the main value throughout the exploration. Now you can link variables using equations or combinations of variables. For example, a link could be created like variable3 = (variable1 + variable2/2).
Generic Response
The new Generic Response can be used to create responses based on a chosen reference solver output file. The enhancement allows you to potentially create responses which are not amongst the current set of out-of-the-box responses supported by Design Explorer.
Run Nominal Run Only
It is now possible to set up a DOE and run only its nominal run, which can be useful to check and debug the model or exploration prior to fully submitting the DOE for evaluation. To run only a nominal run, set the DOE Type to MELS and set the number of runs to 0.
Apply Design Variables to Model
Selecting this new option in the Results Explorer Summary Table will apply all design variable values for the selected run on the model.
Clustering Enhancements
Clustering uses unsupervised machine learning to group exploration results according to user-specified criteria. Prior releases have exposed limited clustering features in the Results Explorer Scatter Plot tool. The updates to clustering include moving it to its own tool in the Results Explorer, where you can now cluster based on load case and result type of their choice. New enhanced visualization tools are available, including the ability to visualize/animate all clusters, overlay results for individual clusters, and create classifications, which will be used via supervised machine learning in coming releases.
Restriction: Currently, clustering is only supported on Windows.

Design Space

New Features

Exoskeleton Workflow
Exoskeleton is a workflow that enables and promotes design exploration of both early concepts and mature structures. The workflow provides insight as to how the structure may need reinforcing to meet a predetermined performance criteria. Two optimization approaches are supported: Topology and Size. Both approaches use 1D elements tied to the structure.


Figure 14. Topology


Figure 15. Size

Extensions

New Features

Pre-Defined Registration of Multiple Extensions Via an Environment Variable
To start HyperWorks with a pre-defined set of extensions, you can now set the environment variable HWX_PLUGINS to add one or more directories from which all extensions will be registered. Click Remove to disable these extensions.


Figure 16.

Enhancements

Block the Disabling of Extensions
The Remove button can be disabled by adding the removable keyword, <entry name="removable" value="true"/>, in the general section of the extension.xml file.
Improved Error Messages
Meaningful error messages are displayed and the extension is not loaded when a ribbon xml is not referenced from inside a profile in the extension.xml file or when tags are not matching.

Resolved Issues

  • The issue with ribbons and toolbars of some extensions not disappearing after an extension has been disabled has been resolved.

Known Issues

The following known issues will be addressed in a future release as we continuously improve performance of the software:
  • Loading extensions covering pre and post-profiles with the HyperMesh profile active will not show the extension loaded in the post clients. The extension needs to be enabled in at least one of the post clients. Similarly, the extension needs to be loaded in the HyperMesh profile if it was loaded first in one of the post profiles.

General

New Features

Multi-Model
It is now possible to have multiple HyperMesh pre-processing windows active within the session, each with its own model. This removes the need to have multiple copies of the application open and reduces memory overhead.
Window and page management:
  • Up to 16 windows per page are supported. Multiple pages are also supported. The organization of all the windows and pages can be saved to a session file.
Model sync:
  • The model view can be synced between windows. If there are two windows side by side and you rotate and/or zoom the model in the first window, the model in the second window will move in unison.
Copy and paste:
  • Entities can be selected for copy in one window and then pasted into the model of another window. This works with most entity types. Selection for copy can happen graphically or through the browser.
  • The follow categories of entities are supported:
    • Physical entities, such as: Elements, Surfaces, and Lines
    • Named entities such as: Parts, Materials, Properties, LoadCollectors, and Optimization Entities
    • Non-named entities, such as: Loads and Vectors
Miscellaneous
A Copy IDs option has been added to the context menu under More > Copy IDs. This will copy the ID range to the clipboard.
Where applicable, common preferences will now adjust multiple HyperWorks applications at once.
A global numeric precision can be set in Preferences > HyperMesh > Appearance > Numeric Format which will affect most dialogs and microdialogs with floating point numbers.

Known Issues

  • Known issues for the File Open/Save dialogs and Message boxes:
    • There are inconsistencies in the appearance of the File Open and File Save dialogs and Message boxes.
    • Based on how they are opened and the available file extension filters in the File Open and Save dialogs, the appearance/style of the dialog can differ from other instances.
    • Some of these dialogs can move behind the main application when clicking elsewhere in the application. This requires you to bring them to the foreground or reposition the application.
    • Figure 25 and Figure 26 show examples of different versions of the File Open dialog:


      Figure 25.


      Figure 26.
  • HyperWorks can hang on re-launch in following instances: if the license is close to expiring, when the license expiration warning dialog opens, and if a non-default browser was active on shutdown.
    • To avoid this, one of the following environment variables can be used:
      • ALM_NO_EXPIRE_WARNING: Disables the expiration warning.
      • ALM_EXPIRE_DAY_WARNING: Specifies the number of days before license expiration, the warning message is given (default is 30).
    • If one of the environment variables listed above is not used to avoid this issue and the issue occurs, deleting the settings files will resolve the issue.
  • In some cases involving multi-monitor setups, if a browser or dialog is dragged from one monitor to another, associated context menus can appear outside the browser/dialog, potentially even on the original monitor.
  • When running in a NICE/DCV environment, there are drawing issues with the HWx toolbelt.
  • On Linux, an error can be seen when importing/opening files from a directory with a name/path containing non-ASCII characters. This error can be avoided by using the encoding system utf-8 command, either in a script or by manually typing it into the Tcl console, before importing/opening the file(s).

Resolved Issues

  • Issues involving some dialogs (Parameter/Criteria Editor, Advanced Selection dialog, and so on) not being visible in certain multi-monitor configurations have been resolved.
  • Performance issues associated with show, hide, and isolate have been resolved.
  • Crash associated with importing an HyperMesh model on top of an existing model has been resolved.

Model Build

New Features

Display Representation
A new lightweight visualization mode of geometry is supported for CAD formats. Supported geometry file formats are: Acis, Catia, CatiaV6, Creo, Inspire, Inventor, JT, Rhino, NX native, NX third party, Parasolid, SLDPRT/SLDASM, STEP, and VDAFS.


Figure 30. Import Geometry


Figure 31. Import BOM
This mode, called Display Representation, is available through import geometry or load representations in the Part Browser. It provides improved import and graphical performance, and offers a convenient way to perform initial inspections of the model. Once the Display Representations have been reviewed, you can optionally load in the full geometry via Representation > Load or submit parts straight to BatchMesher via Representations > Create.
OpenPDM Connection
New PDM Connector, OpenPDM, is now supported. OpenPDM facilitates the better flow of information between different PLM systems. By using OpenPDM connector, HyperMesh can work with any PLM system that integrates with OpenPDM seamlessly.
Classify Tool
The Classify tool, a machine learning tool, has been added in the new AI/ML section of the Assembly ribbon. This tool exploits the benefits of machine learning (ML) to auto-assign labels to parts based on their shape. Each label starts out being manually created and assigned by the user to help the ML model learn what parts look like. Once you have assigned Labels using your own data, you train a model which can then be used to Classify parts on new models. The goal is to automate the process of part identification and classification to reduce manual effort of organizing a large model.


Figure 32.
New Curve Editor
The Curve Editor has been upgraded and given a new look to support some additional features. Tables in the Curve Editor now supports import of tabular data from csv files, direct export to csv, manipulation of data inside a table, such as inserting or deleting rows anywhere in the table, and copy and paste from within or from outside, without any limitations. Curve operations are also supported, such as duplicate a curve, hide, show or isolate a curve with the right-click context menu, Fit all function in the right-click context menu or keyboard shortcut F, and search and filter curve names from within the Curve Editor.
Renumber All
The Renumber All method has been added to the Renumber tool. With this option, all entities of all types in the model are renumbered at once.

Enhancements

Save Representation Workflow Updates
The save representation workflow has been enhanced by allowing the save of only modified parts. Modifications to parts are tracked so we can automatically only save the parts that need saving.


Figure 33.
Sections and Sensor Entities Saved into Part Representations
Sections and Sensor entities are saved into part representations, which better supports Ansys workflows.
Saving Representations Performance Improvements
Performance enhancements have been made to improve the time taken to save representations.
Default Settings Updated for the RBE3 Tool
The default settings of the RBE3 tool have been updated so that the weighting coefficients for independent DOF are a constant 1.0. The distance-weighted coefficient method is still available to use in the tool, but it is no longer the default.

Resolved Issues

Slowdowns with selection and renumbering of large models in the Renumber tool have been resolved.

Model Verification

Enhancements

Intersection Check Function
Intersection Check function reads Part's Database (Digital Signature, BBOX attributes, XYZ intersection locations), compares it with Variant model's attributes and segregates Intersection Reports to Filtered and Non_Filtered groups. If the Part's BBOX, Digital Signature, Intersection Locations are compared with Variant Part's attributes, if the comparison results are within limit set in configuration, then its reports is organized to Filtered Group.


Figure 34.
Intersection Automatic Renumbering of Parts
Intersection will automatically renumber parts if duplicate PID exist, it takes max ID + increment.
Log Information
All log information are unified to have PIDs for Comparison.

Resolved Issues
