Welcome
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.
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
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.

Visualization - Road Tools

To visualize road graphics in MotionView, load the Vehicle Tools Extension and open the Road Tools dialog.

Figure 1. Road Tools Selection Menu

The Road option provides a way to create a surface graphic for the various Altair Road Files.

From the dialog, select the desired road file. All the road types mentioned in the previous sections except 3D Cleat can be visualized.

Figure 2. Road Dialog

In the Road Tools dialog, the Road File path and the Road type must be chosen as shown in the figure below.

Figure 3. Road File Path and Type Selection

The MDL option allows the selection of the file path location where the created road graphics are saved.

Road Sampling can be changed as per your requirement to reduce the time and detail level for producing graphics.

If the [GRAPHICS] block is described in road file, it will be used for the road graphics definition.

In the case of a FLAT road type, a checkered grid is created. The grid size is obtained from the LENGTH and WIDTH value available in [GRAPHICS] block. The square size is obtained from the ROAD_INCR value.

$-------------GRAPHICS
[GRAPHICS]
LENGTH = 160000.0
WIDTH = 80000.0
ROAD_INCR = 500

The road’s origin is shown by the marker in the figure below. If the ROAD_INCR is positive, the grid is created in positive x direction. If negative, the grid is created in negative x direction.
