- 2026 Release Notes
Get Started
Learn the basics and discover the workspace.
Tutorials
Learn more about the Altair HyperWorks suite of products with interactive tutorials.
Startup Procedures and Customizations
Start and configure the applications.
Tool Finder
View a list of deprecated panels and their newer, equivalent workflows.
Manage Files and Data
Create, open, import, and save models.
Sessions and Report Templates
Set up sessions and create report templates.
Interface with External Products
Solver interfaces supported in HyperMesh.
Entities and Solver Interfaces
A solver interface is made up of a template and a FE-input reader.
Browsers
Browsers provide a structured view of model data, which you can use to review, modify, create, and manage the contents of a model. In addition to visualization, browsers offer features like search, filtering, and sorting, which enhance your ability to navigate and interact with the model data.
Sketching
Create and edit 2D parametric sketch geometry.
Topology
Create, edit, and cleanup geometry.
FE Geometry
FE geometry is topology on top of mesh, meaning CAD and mesh exist as a single entity. The purpose of FE geometry is to add vertices, edges, surfaces, and solids on FE models which have no CAD geometry.
Meshing and Elements
Explore the different types of mesh you can create in HyperMesh and create and edit 0D, 1D, 2D, and 3D elements.
Model Build and Assembly
Create, organize, and manage parts and subsystems.
Composites
HyperMesh composites modeling.
Connectors
Create connections between parts of your model.
Morph
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
Skeleton Modeling
Create a reduced ordered model to facilitate optimization at the concept phase.
Design Space
Workflow to support topology optimization model build and setup.
Optimization
Setup an Optimization in HyperMesh.
Design Explorer
Multi-disciplinary design exploration and optimization tools.
Validate
Validate the model built before running solver analysis.
Analyze
Models require loads and boundary conditions in order to represent the various physics and/or physical equivalents to bench and in-use testing.
Axisymmetry
Reduce a full 3D model with axisymmetric surfaces while accounting for imperfections.
Concept Modeling
Tools and workflows that are dedicated to rapidly creating new parts for specific use cases, or amending existing parts. The current capabilities are focused on stiffening parts.
Crash and Safety
Tools used for crash and safety analysis.
Airbag
Use airbag folder utilities and export a resulting airbag in a Radioss deck.
Aerospace
Essential utility tools developed using HyperMesh-Tcl.
Aeroelasticity
Import an aeroelastic finite element model with Nastran Bulk Data format.
Certification
Framework to plug certification methods to assess margin of safety from the model and result information.
PhysicsAI
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or remeshing and without design variables.
Results Data in HyperMesh and HyperView
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data in HyperMesh and HyperGraph
Plot data can be post-processed using both HyperMesh and HyperGraph.
Multibody Modeling in MotionView
MotionView is a general pre-processor for Multibody Dynamics.
Media Files in MediaView
MediaView plays video files, displays static images, tracks objects, and measures distances.
Tabulate Results in TableView
Use TableView to create an Excel-like spreadsheet.
Text Files in TextView
TextView math scripts reference vector data from HyperGraph windows to automate data processing and data summary.
Publishing and Reporting
Create, define, and export reports.

Meshing

New Features

Solid Topology Editing

Automatic mesh update is now available for CAD + mesh and FE geometry when topology editing 3D solids.

Solid topology editing is now supported for the following:

3D tetra mesh and 3D tetra mesh with a 2D skin
First order for CAD + mesh and FE geometry
Second order CAD + mesh

Solid topology editing now requires full association of the nodes to the geometry.

Enhancements

Box Trim

The overall performance has been improved.

Mesh quality has been improved at trim boundaries.

Box calculation has been optimized for accuracy.

Handling of 1Ds and solid elements at box trim boundaries has been improved.

Midmesh

Automatic midmesh extraction now assigns attributes to midmesh surfaces, which enables faster alignment and easier cleanup.

The following new alignment methods have been added for more efficient midmesh adjustments:

Middle
Edge Align
Plane
Cylinder
Offset
Fuse
Copy

FE Geometry

Curvature based is the new method to generate topology from FE geometry. It uses curvature analysis to detect and trace surface features by evaluating how sharply the model bends. Areas with low curvature are treated as flat, while high-curvature regions are examined using principal directions to generate smooth, meaningful lines. It is controlled by three options:

Edge feature angle
Vertical filter
Parallel filter

Resolved Issues

Some bugs were resolved which has improved meshing compatibility with embedded 1Ds.
Some bugs were resolved which significantly enhanced the performance of Element Quality Color mode.
