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.
- Manage Parts
- Manage Subsystems
  - Open the Subsystem Browser
    Use the Subsystem Browser to create, organize and manage CAE subsystem level models.
  - Create Subsystems and Subsystem Instances
    To create subsystems, you can use drag-and-drop across browsers or the Organize functionality.
  - Manage Subsystem Representations
    A single subsystem can have multiple CAE representations that can be loaded into the session interchangeably.
  - Manage Subsystem Revisions
    Manage, control, and update Major, Study, and Library subsystem revisions using the Subsystem Library.
  - Manage Subsystem Configurations
    Group unique subsystems together into subsystem sets and organize both subsystems and subsystem sets into configurations. In cases of subsystem hierarchy, only the top level subsystem can be added to a set or configuration; this will automatically take all of the hierarchy into the set/configuration.
- PostgreSQL Installation and Configuration
  Also referred to as Postgres, PostgreSQL is an object-relational database management system with emphasis on extensibility and standards compliance.
- Section Library
  Use the automotive section library for rapid concept development in the early phases of the vehicle design process.
- Organize Entities
  Use the Organize tool to move or copy entities into their proper destinations.
- Match Parts
  Automatically group selected parts into part sets based on comparison method and criteria selected.
- Classify Parts
  Set up and use machine learning (ML) models to automatically classify parts under user-defined labels and into part sets.
- Renumber Entities
  Use the Renumber tool to review and organize the IDs of model entities.
- Reorder Entities
  Change the order of named entities in database.
- ID Management
  Manage the IDs for the entities that you create, and define ID ranges for the entities in each Include file in order to avoid ID duplication across files.
- Perform Representation Operations
  Use the Reps tool to perform representation operations for parts and subsystems.
- Manage Scenarios
  Scenarios are a mechanism to apply controls to engineering entities.
- Mechanism Browser
  Create and articulate a kinematic mechanism based on FE mesh using the Mechanism Browser.
- Model Update
  Compare and update a current HyperMesh session with an incoming model and generate comparison results.
- Model Verification
  Perform automatic checks on CAD models, and identify potential issues with geometry that may slow down the meshing process using the Verification and Comparison tools.
- Systems
  Local coordinate systems can be used for setting up loads/boundary conditions that do not act in the global axis direction, transforming results, defining material orientation, and many other operations.
- Create Vectors
  Define vectors in 3D space.
- Assign Properties and Materials
  Define physical and mathematical characteristics of parts.
- Load Materials From the AMDC
  Import materials directly from the Altair Material Data Center (AMDC).
- Create Mass Balance
  Automatically distribute masses on nodes, properties, or parts to match user-defined target mass and center of gravity (COG).
- Generate Contacts Automatically
  Use the Auto Contacts tool to determine contact interfaces between selections of components or elements. Based on the user-specified options like proximity tolerance, surface creation method, main surface type, and secondary type, the tool generates contacts based on set segments or node and element combinations.
- RBE2s, RBE3s, and MPCs
  Create, review, and edit RBE2/RBE3 elements and MPC equations.
- Create and Edit Curves
  Use the curve editor to create and plot XY curves.
- Analytical Rigid Surfaces
  The Abaqus solver offers the flexibility of modeling rigids as surfaces using primitive geometry.
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.

Manage Subsystem Revisions

Manage, control, and update Major, Study, and Library subsystem revisions using the Subsystem Library.

About Subsystem Library and Revisions

The Subsystem Library is an integral part of data management and revision control within the Subsystem Browser.

The Subsystem Library serves as a centralized library of HyperMesh subsystems, which in turn facilitates the collaboration between simulation teams. You must be connected to a subsystem library to access all subsystem library related options.

Revisions

In the Subsystem Browser, the Revision column displays the Major revision, Study revision, and Library revision. All appropriate workflows have entry or access points to the subsystem library, enabling quick and easy access to previous revisions or simply generating new revisions.

You can review the following revisions in the Entity Editor:

Major Revision: Depicts a change or set of changes that have been finalized and released for further review. In most cases the Major Revision should be mapped to the PDM Revision, but you can modify it.
Study Revision: Created locally to track experimental changes or prototyping changes that may or may not be published. The purpose of the Study Revision is to manage design and prototype exploratory concepts. You can modify the Study Revision.
Library Revision: Locally, published revision within the Subsystem Library. You cannot modify the Library Subsystem Revision. It automatically increments on each save when major and study revision are not changed

Create, Add, and Connect to Libraries

Create, add, and connect to libraries.

For more information refer to Manage Part Revisions.

Sync Library Revisions

Sync the in-session library revision with the latest available revision in the Substation Library.

If someone else has made changes to the library and your session is not up-to-date with the library, use Sync to recheck the library for the latest data, making the latest library revision available the next time a user loads from the library.

Before you can sync library revisions, you must Create and Connect to Libraries.

In the Subsystem Browser, right-click on a subsystem and select Library > Sync from the context menu.
