What's New
View new features for Altair HyperWorks 2024.
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.

- Assembly Tools
  Create an assembly structure from a .csv file definition.
- Load/BCs Tools
- Connection Tools
  - Fastener Setup
    Create node-to-node CBUSH elements at the connector locations point/node or line.
  - Convert CFAST Elements
    Use the cfast converter tool to convert CFAST elements into CBAR/RBE3 (spiders). For thermoelastic analysis, the CFAST has no thermal expansion coefficient. CBAR is thermoelastic compatible.
  - Stuck Node Creation
    Use the Stuck Node Creation tool to create (double) RBE3 connection to "stick" nodes on QUAD or TRIA elements to make the node displacements following the element ones.
  - Create Linear Gaps
    Use the Linear Gap tool to create linear gap analysis cards for Nastran and OptiStruct.
  - Sewing Tools
    Connect two dissimilar 2D shell meshes using RBE3 connection.
  - Create 0D Elements Between Disconnected Nodes
    In the steps below, you will create zero length elements and review.
  - Create 0D Elements Between Connected Nodes
- Spatial ID Manager Tools
- Display Tools
- Export Tools
- Set Tools
- System Tools
- Node Tools
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
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data
HyperGraph is a data analysis and plotting tool with interfaces to many file formats.
Multibody Modeling
MotionView is a general pre-processor for Multibody Dynamics.
Media Files
MediaView plays video files, displays static images, tracks objects, and measures distances.
Tabulate Results
Use TableView to create an Excel-like spreadsheet.
Text Files
TextView math scripts reference vector data from HyperGraph windows to automate data processing and data summary.
Publishing and Reporting
Create, define, and export reports.
Collaboration Tools
Explore, organize and manage your personal data, collaborate in teams, and connect to other data sources, such as corporate PLM systems to access CAD data or publish simulation data.

Fastener Setup

Create node-to-node CBUSH elements at the connector locations point/node or line.

Restriction: Only available in the OptiStruct and Nastran user profiles.

From the menu bar, click Aerospace > Connections > Fastener setup.

The methods that are available are Huth Formula, User defined (Huth) and Rutman. The supported element types are rbe3_cbush_rbe3, cbar (rigid), cbush, cfast_elem, cfast_prop and HiLock.

When using fastener setup, the nodes need to be opposite of each other when two plates are connected (congruent meshes). If the meshes are not congruent, it is recommended to use RBE3-CBUSH-RBE3 or CFAST connector types.

Note: You must provide the rivet diameter, or you should have axillary lines to represent the diameter.
