The Simcenter Hypermesh, Hyperview and Hypergraph suite helps engineers build finite element models, create and manage assembly connections, assess simulation results, generate plots, and correlate simulation outputs with physical tests. Siemens groups the improvements in version 2026.1 under four themes: Model the complexity, Explore the possibilities, Go faster and Stay integrated.

Key highlights of this release include:

• Find and reuse previously meshed parts with Retrieve with ShapeAI;
• Edit FE geometry and create connectors directly on complex models;
• Extend multicore post-processing, plotting, HTML reports and curve correlation based on ISO/TS 18571:2024;
• Significantly reduce model opening times, solver deck export times and large assembly processing times;
• Integrate Teamcenter operations through PDM Live and enhance CAD/solver compatibility.

1. Reusing Existing Meshes with Retrieve and ShapeAI

One notable addition in Simcenter Hypermesh 2026.1 is Retrieve, which uses ShapeAI to search for previously meshed parts based on geometric similarity.

Rather than relying on exact names, part numbers or revisions, the tool compares the shape of the current object with the team's part library. Matching results are ranked, and a saved mesh representation can then be loaded and automatically positioned in the working session. This approach enables teams to reuse meshing work from earlier projects even when naming conventions and folder structures differ.

• Reduce the need to remesh parts that have already been processed;
• Leverage existing part libraries without a separate data migration project;
• Support collaboration across design teams and locations.

2. Editing FE Geometry Directly on the Mesh

FE Geometry Editing expands the ability to make local changes directly in the meshing environment, reducing the need to switch back and forth to CAD software.

Version 2026.1 adds curvature-based FE geometry reconstruction, surface partitioning with offset curves, improved midmesh generation within CAD solids, automatic anchoring of attachment nodes during Remesh or Rebuild operations, and Batchmesher washer handling for 3D holes. These enhancements target repetitive adjustments made during finite element model finalization.

• Reduce the number of returns to CAD for minor geometry changes;
• Preserve attachment behavior when updating meshes;
• Extend familiar 2D washer workflows to 3D holes.

3. Automating Connectors and Assembly Connections

Simcenter Hypermesh 2026.1 improves workflows for creating connections at subsystem boundaries, particularly for body-in-white (BIW) structures and aerospace applications.

Auto-Connect introduces a Different Subsystem Only mode, which creates connections exclusively between different subsystems. Other additions include Seam Quad RBE2-RBE3 with heat-affected-zone support, Mesh Independent welds, HiLock connections through mixed composite solid–shell assemblies, and step-hole-aware attachments. These capabilities help engineers standardize assembly connections and reduce connector rework before exporting solver decks.

• Improve control over connections at subsystem boundaries;
• Reduce manual inspection and repair of large assembly models;
• Support complex welded and composite connection scenarios.

4. Hyperview Multicore as a Default Configuration

In version 2026.1, users can configure Hyperview Multicore as the default profile for workflows that support multicore processing.

The Multicore profile continues to gain functionality, including GLB/PPT-GLB export and HTML export of complex results, while preserving existing session and template behavior. This is particularly relevant for analyzing large crash and safety datasets. However, Multicore does not yet offer full feature parity with Hyperview Classic; Classic is still required for workflows not yet supported.

• Take advantage of multicore processing for suitable post-processing tasks;
• Continue using existing sessions and templates;
• Select Classic when a workflow is not supported by Multicore.

5. Plotting and Reporting Directly in Hypermesh

Plotting and Reporting closes the gap between model development and simulation result review.

Hypermesh can read result files to generate line charts and complex charts in multi-window layouts. Chart Manager has been optimized when reopening sessions containing many plots: a benchmark presented in the release slides shows that opening a session with 250 charts decreased from 288 seconds to 28 seconds. HTML report export has also been expanded to support modal animations and synchronized dashboards.

• Review routine results within the same model-building environment;
• Reduce the time needed to reopen sessions containing numerous plots;
• Share complex results through more informative visual HTML reports.

6. Hypergraph Curve Correlation with ISO/TS 18571:2024

Simcenter Hypergraph 2026.1 adds support for ISO/TS 18571:2024 to assess the correlation between simulation curves and experimental test data.

The tool supports updated scoring metrics and broader model-to-test validation workflows. The new standard complements existing methods, including CORA and ISO 18571, while solver data readers have also been updated. These improvements are especially relevant to crash and safety model validation teams, where quantitative methods and reproducible results are critical.

• Apply the 2024 edition of the curve correlation standard directly;
• Reduce the need to develop custom correlation-scoring scripts;
• Support model validation using real-world test data.

7. Accelerating Operations on Large-Scale CAE Models

Performance on large models is a major focus of the 2026.1 update.

Opening a model containing 36,000 components / 66,000 parts decreased from 16 to 4.5 minutes; for a model with 72,000 components / 132,000 parts, the time fell from 45 to 11 minutes. Exporting a solver deck for a model with approximately one million elements decreased from 17 to 2 minutes, while the Show All entities operation dropped from 80 to 11 seconds. These are before-and-after measurements for the stated models and workflows, not guaranteed speedups for every machine or dataset.

• Reduce waiting times when opening large projects;
• Accelerate solver deck export and display updates;
• Enable engineers to complete more review cycles in a single working session.

8. Optimizing Subsystem Node Equivalence and Component Replace

Workflows involving subsystems and assembly configuration changes have been further optimized to reduce processing times for large enterprise-scale models.

Subsystem Node Equivalence decreased from 5 hours to 3 minutes on a representative model, and from 4 days to 54 minutes on a large enterprise model. For Component Replace, dialog display time dropped from 180 to 15 seconds, while mapping preview for a 1.6-million-element model decreased from approximately 34 minutes to around 17 seconds. Overlay operations across large variant sets containing 100 to more than 750 parts were reported to be about 90% faster.

• Substantially reduce subsystem boundary processing times;
• Support component replacement and multi-variant comparisons within a session;
• Improve operating efficiency without requiring changes to existing workflows.

9. Direct Teamcenter Integration and Subsystem Instance Link Management

Under the Stay Integrated theme, Hypermesh 2026.1 strengthens the connection between CAE operations and enterprise PLM platforms.

PDM Live enables Teamcenter Check-In, Check-Out and Cancel Check-Out directly within Hypermesh. In addition, Subsystem Instance Link enables repeated subsystems to be created and synchronized: editing one instance can update other linked instances. Expression-based query searches have also been added to help manage complex part structures.

• Reduce switching between CAE software and PLM interfaces;
• Keep repeated assemblies, such as brackets or symmetric configurations, synchronized;
• Facilitate cross-team collaboration on large simulation programs.

10. Expanded CAD and Solver Data Compatibility

Version 2026.1 includes more than 70 CAD interoperability enhancements and updates to solver interfaces to better support current software ecosystems.

Supported CAD versions include NX 2506/2512, Inventor 2026, SOLIDWORKS 2025, Parasolid 38.0 and JTOpen 11.8. Other additions include a new IGES reader and a Skip Metadata option when importing large CAD assemblies. Solver-related updates include LS-DYNA R16 keywords, SET3 support for Simcenter Nastran, battery cell modeling and curved pipe beams in OptiStruct, and new Radioss material laws.

• Reduce barriers to data exchange between CAD and CAE;
• Speed up assembly imports by skipping metadata when appropriate;
• Continue supporting new solver data formats and element types.

Overall Value of Simcenter Hypermesh, Hyperview and Hypergraph 2026.1
