What is Altair HyperMesh?

HyperMesh is the market-leading, multi-disciplinary finite element pre-processor which manages the generation of the largest, most complex models, starting with the import of a CAD geometry to exporting a ready-to-run solver file.

HyperMesh supports a wide variety of CAD and solver interfaces, making it a perfect solution for most industry verticals and domains. With its advanced geometry and meshing capabilities, HyperMesh provides an environment for rapid model generation. Generating high-quality mesh quickly is just one of HyperMesh’s core competencies.

For complex sub-system generation and assembly, HyperMesh has advanced model assembly tools. Modeling of laminate composites is supported by advanced creation, editing and visualization tools. Design changes can be made easily via mesh morphing and geometry dimensioning.

Pre-processing for Complex Assemblies

Complete model setup of even the most complex simulations across multiple domains and industries, including automatic and semi-automatic shell, tetra, and hexa meshing capabilities.

Open-architecture Design

Robust, common FEA modeling framework with the broadest set of direct CAD and CAE interfaces, with the ability to define custom integrations.

Automated Model Build

Highly efficient for part level model building and assembly, representation and configuration management. Intelligent connector tools and auto contact help with final model assembly.

Best In Class Meshing

HyperMesh presents users with an advanced suite of easy-to-use tools to build and edit CAE models. For 2D and 3D model creation, users have access to a variety of mesh-generation capabilities, as well as HyperMesh’s powerful automeshing module.

HyperMesh holds strong features for modeling highly complex composites structures. Ply entities allow defining the shape of individual layers based on geometry or elements. The laminate entity defines the stacking order of a composite part. The composites definition is generic and can be realized into many solver profiles.

For review purposes composites structures can be visualized in 3D, individual layers isolated and ply orientations visualized graphically.

For a highly efficient workflow the CATIA reader has been enhanced to read composite definitions, such as ply shapes, material and ply orientations, directly from the geometry file. Fibersim drape data can be imported in a very similar way. HyperMesh offers sophisticated mapping algorithms to transfer the geometric input data to an FE mesh and associated properties.

CAD Interoperability
HyperMesh provides import and export support for industry-leading CAD data formats. Moreover, HyperMesh has robust tools to clean up imported geometry to allow for the efficient generation of high-quality meshes. Boundary conditions can also be applied directly to geometry for automatic mapping to underlying elements.

Collaboration Tools
HyperMesh Collaboration Tools are available with the standard installation and work out-of-the-box. Users are enabled to work in a powerful and truly collaborative environment. The Explore dialog is tightly integrated into all HyperMesh file dialogs and allows for efficient searching of databases and retrieving of files. The Organize Browser helps to structure simulation data and file versions. Personal or team data can be efficiently managed to ensure that always the latest file versions will be used. Keyword search allows efficient research of databases. Connect is the connection to a common team database or corporate PLM systems. Files can be retrieved or uploaded from or to the database. The Collaboration tools also contain a material library allowing searching and filtering a corporate material database.

Connectors are geometric entities used to connect geometry or FE entities. They are used to create spot- and seamwelds, adhesives, bolts or masses. Connectors can be realized from geometric entities into various solver specific FE representations. It is possible to unrealize them to change the representation to a different type or solver profile on the next realization. Connectors contain their location, linking partners, connection rules and realization types. They can be created manually, absorbed from FE existing FE connections or imported and generated from text files.

Customize HyperMesh to Fit Your Environment

  • Configure the HyperMesh Interface: Customize your modeling experience through an easy-to-use interface containing drag-and-drop toolbars, configurable pull-down menus and keyboard-controlled shortcuts.
  • Custom Utilities: Create custom applications that are fully integrated within the HyperMesh interface.
  • Solver Input Translators: Users can extend HyperMesh’s interface support by adding input translators to read different analysis data decks.
  • Solver Export Templates: Export templates allow the HyperMesh database to be written out to user defined formats for non-supported solvers.

High Fidelity Meshing

  • Surface meshing
  • Solid map hexa meshing
  • Tetra meshing
  • CFD meshing
  • SPH meshing

Mesh Morphing
HyperMorph is powerful solution for interactively and parametrically changing the shape of a finite element model. Its unique approach enables rapid shape variations on the finite element mesh without sacrificing mesh quality. During the morphing process, HyperMorph also allows the creation of shape variables, which can be used for subsequent design optimization studies.

Batch Meshing
Using Altair® BatchMesher™ is the fastest way to automatically generate high-quality finite element meshes for large assemblies. By minimizing manual meshing tasks, this auto-meshing technology provides more time for value-added engineering simulation activities. BatchMesher provides user-specified control over meshing criteria and geometry clean-up parameters as well as the ability to output to customized model file formats.

CAE Solver Interfacing
HyperMesh supports a host of different solver formats for both import and export. Along with fully supported solvers, HyperMesh provides a completely tailored environment (user profile) for each supported solver. It also provides the flexibility to support additional solvers through a unique and straightforward interfacing language.
