What's New
View new features for Altair HyperWorks 2025.
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.

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.
- Create and Assign Structural Properties
  Structural properties are meant to be placeholders that hold local information, that can change from one structural element to another, useful for method evaluation. They usually contain extra information not directly available from FE entities or results.
- Create Beam Structural Elements
  Beam structural elements can be meshed with 1D elements or shell elements.
- Create Panel Structural Elements
  The Panel tool recognizes metallic panels or composite panels, which lead to two different configs as the structural property and method available for these configs are different.
- Create Rivet Structural Elements
  The Rivet tool recognizes rivets modelled as a collection of Shell-1D-Shell patterns. The body between two shells is made of a single 1D element. However, it detects a rivet as a multi-layered connection.
- Create Spring Structural Elements
  The Spring tool recognizes CBUSH connections and absorbs them as springs.
- Import From File
  From the Certification Browser, import several designpointsets with designpoints and structural properties in bulk from the context menu.
- Create Generic Structural Elements
  Use the Generic tool to collect elements and free body sections in designpoints.
- Organize Structural Elements
  Besides the creation of structural elements, you can reorganize existing entities in new designpointsets, the aim being to collect structural elements on which the same set of methods will run (for a given set of loadcases).
- Methods
  Each designpointset can have a different set of methods (designpointmethod entities) assigned to it.
  - Create Methods
    Create designpointmethod entities in HyperMesh using a template definition. In such templates, method prototypes are defined as a reference to functions where input arguments are mapped to attributes in the database.
  - Assign Methods
    To run methods on designpointset entities, the methods must first be assigned. Creating methods simply adds new designpointmethod entities to the database, but no reference is added to any designpointset.
  - Author Custom Methods
    Register new methods and save/import existing libraries. topics/pre_processing/aerospace/method_manager_r.html shows these steps in more detail.
  - Method Manager
    Use the Method Manager dialog to create new methods and populate libraries or import existing libraries from .xml files, as explained in previous chapters.
  - Built-In Library of Methods
    By default, HyperMesh comes with a set of methods. These methods are always available even if you register your own custom methods.
- Run Methods
  Designpointmethod entities can be evaluated, looping across loadcases, either directly on a selection of elements (if valid) or collected in designpointsets.
- Contour Methods
  Contour a single designpointset or designpointmethod. Method inputs and outputs are available to contour with aggregations.
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.

Beam Failures

The Beam config has two subtypes: Beam_member and Beam_shell. The first is made of 1D elements while the second points to freebody sections. Both configs come with their flavor of the same actual methods:

Stringer Axial Stress
Stringer compressive buckling

The Stinger Axial Stress is a simple method which calculates the Compressive/Tensile margin of safety as:

MS= [(Compressive Stress limit)*(section Area)/(Axial Force)] -1; (resp. Tensile Stress limit)

In the case of freebody sections, Axial Force is mapped to the freebody resultant Fx.

The compressive buckling method evaluates

$M S = F_{c c} / σ_{x} - 1$ with:

$σ_{x}$ : average axial stress as (Axial Force)/(Section’s area)
$F_{c c} = F_{c y} * (1 - .272 (L' / ρ) / π * \sqrt{E / F_{c y}})$
$F_{c y}$ : material compressive stress limit
$L' = (structural property L e n g t h) / \sqrt{K_constraint}$
- K_constraint = “constraint coefficient” on structural property. Def=0.0699
$ρ$ : beam section’s radius of gyration
E: material young’s modulus
