Welcome
What's New
View new features for Altair HyperWorks 2024.1.
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.
- Dummy Positioning
  Position a dummy model using the Dummy Browser.

- Barrier Positioner
  Use the Barrier Positioner tool to automatically get the impact barrier into position, based on the selected crash regulation.
- Bus Rollover
  Use the Bus Rollover tool for the automatic recognition of the unstable position of the bus, the automatic recognition of the impact position of the bus, and the automatic creation of loadcase for impact simulation.
- Ejection Mitigation
  Use the Ejection Mitigation (EM) tool for the automatic target marking according to FMVSS-226 rules, automatic positioning of the headform impactor, and the automatic export of ready-to-run solver decks for all of the selected impact locations.
- IP Impact
  Use the IP Impact tools to automatically calculate the instrument panel (IP) testing area according to the regulations FMVSS201 and ECE-R21, position the headform impactor, and export ready-to-run solver decks for all the selected impact locations.
- Pedestrian Impact
  The Pedestrian Impact tool automates the vehicle marking, impactors positioning and the export of solver decks with minimal input, therefore reducing the full process lead time.
- FMVSS 201 U – Upper Interior Head Impact
  Use the Fmvss201U Marking tool to streamline the vehicle marking process by incorporating necessary input data for vehicle parts.
- Safety Tools
  Use the Safety ribbon to access crash and safety post-processing tools.
- Altair Safety Report Manager
  The Altair Safety Report Manager (ASRM) is a fully customizable automatic report generation utility for crash and safety regulations.

Update Upon Motion

Use the Link Dummy Mechanism to update dummy and seat motion.

After changing the position of a dummy and seat, the seatbelt tool can automatically update the full seatbelt system.

In the Entity Editor, activate the Link Dummy Mechanism checkbox.

If the Link Dummy Mechanism is not activated, you can still update on demand by right-clicking on the appropriate seatbelt system and selecting Update from the context menu.
