Altair HyperMesh 2022.1 Release Notes
Aeroelasticity
Resolved Issues
- The Aeroelasticity Browser no longer shows empty folders.
- Flutter curves were not working for OptiStruct input files on Linux. This has been fixed.
- The Move tool now shows location info in local coordinate systems.
API
- HyperWorks Context APIs
- A new set of Tcl API commands has been added to allow you to programmatically interact with HyperWorks contexts. The list of commands can be found in the Context Commands section of the HyperWorks Reference Guide.
- HyperMesh Panel APIs
- The HyperMesh panels are being gradually phased out with the complete removal scheduled for the v2023 release. More than 400 individual panels and subpanels have been already removed in HyperWorks v2022.1. The panel API commands will be also deprecated and removed with the v2023 release. They remain supported until then. However, referencing a deprecated panel in these commands will result in a silent failure. For more details and the full list of new features and enhancements, see the 2022.1 API Programmer’s Guide section of the HyperMesh Reference Guide.
Browsers
Enhancements
- Browser population with selected content
- Working with selected contents in browsers is now supported. You can
pick the required entities, including Nodes and Elements, to be shown in
respective browser and further review and edit data with attribute
columns.
Figure 1. - Attribute Column support for list selectors
- All list selectors including Main and Secondary fields of a contact can
now be added as columns in browser for bulk review and editing of
data.
Figure 2. - Filtering support in ID manager
- Search and filtering with Auto complete, Columns filters, and Predefined
filters, is now supported in the ID manager.
Figure 3. - Massive performance improvements
- Performance improvement (60-80%) in invoking context menus in the Model Browser.
- Embedded Entity Editor in Ansys interface
- Embedded Entity Editor is now supported in the Ansys interface for quick review and editing of referenced entity attributes.
- Context menu reorder
- Context menus have been reordered to have a consistent order of menus across entities, folders, and browsers.
- API to control browser updates
- Public API hm_blockbrowserupdate <0/1> has been added to control browser updates while running scripts.
Resolved Issues
- Performance issue while showing data in the Entity Editor for load steps with multiple references.
- Collected entities were not updated correctly upon making the respective collectors inactive.
- Idle selector would switch to all previously accessed entities during model load.
- Review of collected entities was not dynamic.
- Elements and Geometry visibility icons would fail to update when browser is filtered with string values.
- Filtering of Part representation column with <Empty> would not work.

Certification
Enhancements
- Generic Structural Element
- It is now possible to directly select Components, Sets, or Parts while
creating generic structural elements. Only Sets of elements are
supported. On Run, the method is evaluated on elements from
Components/Parts/Sets.
- Split option "none" or "by entity" generates a single structural element or one per entity selected.
- DesignpointMethod Evaluation System
- The system used to extract result information is no longer set at the
Designpoint Set level but at each method level. It is also possible to
define a user system for result extraction. If a defined extraction
system is not compatible with data query, then the Global system is used
instead.
The System option is removed from the Run tool while running on elements since it is controlled per method.
- Built-in method JointLoad
-
- Method arguments are reworked as datanames instead of metadata.
Options now have tooltips to describe option behavior.
- Legacy files will be updated if method is Run to use new style arguments.
- New argument "Extraction" is added to control output:
- All - outputs all debug info (same as 2022) leading to 85 columns in table.
- Forces and Fluxes - outputs fastener forces as well as far field fluxes (Nxx/Nyy..) but without all debug info leading to less columns.
- Fastener Force - outputs only fastener forces Fx,Fy,Fz and max tension.
- Method arguments are reworked as datanames instead of metadata.
Options now have tooltips to describe option behavior.
-
Figure 4. - Built-in attributes mapping for OS H3D files
-
- Added support of native H3D files when mapping function arguments with result data.
- 1D Forces & 1D Moments as well as Stress are correctly mapped and no more need user attributes defined in library.
Resolved Issues
- Built-in method JointLoad
-
- Chaining a method after JointLoad was broken in version 2022.0
and is solved in 2022.1.
- As a result, the JointLoad table has an extra column added for entityid.
- Box Angle (renamed as Material Angle) used to only rotate the extraction box but was still extracting forces and fluxes in pierced shell material system. It now properly query components in rotated system.
- Chaining a method after JointLoad was broken in version 2022.0
and is solved in 2022.1.

- Absorb properties in Ansys profile updated for direct property assignment
- Import of Catia Stack-up file
- Instance ply editing forces pop-up for datanames which should not require conversion to main ply
- Laminate export to spreadsheet if one or more plies missing material assignment

-
- Element based analyses for ply-based properties do not consider draping data of the element, but the nominal layup definition. Realize the laminate, if needed, to get access to the draped laminate properties.
- Limitation: Composite Plate Load strain is handled as initial strain when combined with thermal load. Option to use strains as boundary conditions is not yet available.
- Limitation: Temperature-profile through laminate thickness is assumed to be linear. Potentially different thermal conductivity of materials is not considered.
