Enhancements
- Two links only option
- New option “Two links only” is added to Link option attribute of all seam and area connectors. This is a local option which can be set on individual connector. If link option is set to “two links only,” based on the projection on the links, the connector realization will have only best two links considered.
- Build mesh after imprint
- New option “After Imprint” is added to spot and seam connectors which undergo imprint. This is a global option. With connector realization the mesh around imprint will be built based on Rebuild or Remesh option. By default, “After Imprint” is set to Rebuild.
- Auto trim
- New global option “Auto Trim” is added to seam connectors. Enabling this option will trim the ends of seam connectors based on the average projection length of all the test points. It also trims the connector ends if there are no projections.
- Multiple connectors at proximity
- If seam connector which generates HAZ are at proximity the logic of realization in enhanced such that more connectors gets successfully realized.
- Disassociate FE
- New option “Disassociate FE” is added in connector browser context menu under "Edit ". It breaks the link between FE and connector. The connector turns to modified state.
- New formulations
- For seam quad LTB and seam rigid LTB connector, new formulations T1, T2, Tmin, Tmax and pitch size are added to thickness dependent dimensioning schema.

New Features
- Highlights
- Comparison function is enhanced with auto comparison, AI comparison and plastic parts comparison.
- Auto Comparison
- “Auto” parameter is added under config/compareunifed to compare parts that are moved in 3d axis (translation, rotation, symmetry) at once. For CAD vs FE and FE vs FE the matched percentage will be displayed without coloring the unmatched elements. By default, this parameter is turned OFF. For CAD vs CAD unmatched entities will be displayed in report and transformation matrix will be exported to YYYYMMDD_HHMMSS_transformationmatrix.txt file under report path.
- AI Approach
- “AI-approach” parameter is added under config/compareunifed to combine AI based logic for the comparison. AI and Shape based comparison will be executed simultaneously and best results will be displayed in the report. Results will be marked as (AI) without displaying unmatched entities in the reports. By default, this parameter is turned OFF.

- Zero value is not be accepted for Comparison tolerance.
Stress Tools
New Features
- Beam Config
- New Design Point Config Beam is available with 3 types: Beam, Beam
Member, and Beam Shell. The latter supports Freebody section as a design
point which enables you to perform beam certification methods on shell
elements. Two methods ship with the installation:
- Beam Compressive Crippling
- if sx < 0, MS = sx/Fcc -1; with Fcc= Fcy*(1- Kcrippling*(L’/ r)/p*sqrt(E/Fcy))
- Beam Axial Stress
- if sx > 0, MS = sx/Ftu -1; if sx < 0, MS = sx/Fcy -1
- Chain Methods
- A method can take its arguments as a result from a previous method. This enables you to chain methods one after the other and include some sorting (either spatial aggregation or load case enveloping). JointLoad method for Rivet is not yet a valid method for chaining.
Enhancements
- Dockable Certification Browser
- Certification browser and is now a (un)dockable browser of HyperWorks.
- Contouring Method
- Enhance Contouring UI to support sorting options. Depending on method output and Design Point config, values can be per load case, per layer, or on element vs. on design point.
- Load case and Layer selection, if applicable, can be set to “Envelope”.
The Sort key (min|max|absmin|absmax) will be applied to perform
aggregation lively on Contour. Similarly, if method output is per
element but you select Entity Column to “DDP” it will perform an
aggregation using the same sorting key. Only one key is valid for all
aggregations at a time.
Figure 7. - Consolidated Table
- Whenever multiple methods are assigned to a Design Point Set, a consolidated table is added which enables you to find the most critical method per location. Method registration needs to tag one output as “Marginofsafety” to be considered a comparison key and be registered in the consolidated table. Contour invoked from Design Point Set level will select the consolidated table. Sort key will be used to compare method MS.
- API to run method on mark of element
- *rundesignmethod API can now run a method directly on a mark of element without Design Points.
CAD and Solver Interfaces
CAD Interface
Enhancements
- Updated version support
-
- 3DExperience R2020X
- AVEVA Marine E3D 3.1
- CATIA V5-6 R2020
- Inventor 2020
- NX 1899 (third-party reader, native reader support was previously available)
- SolidWorks 2020
- Timeout
- A new timeout feature has been added to the JT and NX native readers.
When enabled, the reader is checked periodically to see if it has
crashed or still alive. If the reader has crashed or is still alive and
running longer than the timeout value, it will be killed. This is
exposed as an option in the relevant .ini files as
well as in the Import GUI as "Timeout". This addresses problems of hangs
and crashes in the reader itself. It does not cover after the reader is
finished and the data is passed to HM, which is not subject to the
timeout.
This is beneficial for loading representations, as a crash/hang in the reader when importing a single leaf of a BOM tree will not prevent the rest of the files from loading. Only the leaves with problems will be skipped.
Please note that for single files, or monolithic files, nothing will be imported if there is a crash/hang in the executable, as this is a per-file operation.
Resolved Issues
- Miscellaneous robustness and performance improvements.
- NX naming scheme is followed when splitting components "by body" with NX native reader.
