Altair HyperMesh

Product information

High-Fidelity Finite Element Modeling

Altair HyperMesh is a high-performance finite-element pre-processor that provides a highly interactive and visual environment to analyze product design performance. With the broadest set of direct interfaces to commercial CAD and CAE systems and a rich suite of easy-to-use tools to build and edit CAE models, HyperMesh provides a proven, consistent analysis platform for the entire enterprise.

1. Benefits

Open-Architecture Design

Combining the broadest set of direct CAD and CAE interfaces with user-defined integrations, HyperMesh fits seamlessly within any simulation environment.

High-Speed, High-Quality Meshing

Streamlines the modeling process and provides a suite of tools to model even the most complex geometries.

Model Build and Assembly

HyperMesh Part Browser is dedicated to part level Model Build and Assembly, Representation management and Configuration management. A bi-directional link to PDM enables the seamless import and export of the model hierarchy. The Part Library is used to manage, control, and update Library Part revisions and serves as a centralized library of HyperMesh parts, which in turn facilitates the collaboration between simulation teams both locally and abroad.

Increases End-User Modeling Efficiency

Using sophisticated batch meshing technology, HyperMesh eliminates the need to perform manual geometry clean-up and meshing, thus accelerating the model development process.

Advanced 3D Model Visualization

3D visualization of all element types (1D, 2D and 3D elements) within an FEA model eases model checking and visual verification.

Model Setup

A variety of sophisticated tools help with efficient model setup. The ID Manager ensures that all entities of a model even across or per include files adhere to a specified numbering scheme of a workgroup or a company to ensure modularity. HyperMesh provides connector technology, a highly automated way for assembly of hundreds of parts with spot- and seam welds, adhesives or bolts. Automated contact management tools are a huge time saver when defining contacts between individual parts.

Composites Modeling

Ply and laminate entities facilitate composites modeling in terms of individual layer shapes and their stacking sequence. CATIA CPD and Fibersim readers extract composite data and map it onto FE meshes automatically. Plies and ply angles can be visualized in 3D for easier model verification.

2. Meshing Capabilities

HyperMesh presents 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 Altair HyperMesh’s powerful automeshing module.

Surface Meshing

The surface meshing module in HyperMesh contains a robust engine for mesh generation that provides unparalleled flexibility and functionality. This includes the ability to interactively adjust a variety of mesh parameters, optimize a mesh based on a set of user-defined quality criteria, and create a mesh using a wide range of advanced techniques.

Solid Meshing

Using solid geometry, HyperMesh can utilize both standard and advanced procedures to connect, separate, or split solid models for tetra-meshing or hexa-meshing. Partitioning these models is fast and easy when combined with HyperMesh's powerful visualization features for solids. This allows less time spent preparing geometries for solid meshing. The solid meshing module quickly generates high quality meshes for multiple volumes.

Mesh Controls

Mesh controls promote meshing automation for surface, batch meshing, adaptive and volume mesh generation. Detailed local and global control of mesh parameters for either the entire model or for individual features and regions of the geometry are possible. Mesh controls can be saved in the database or exported and reused in other models, promoting standardized mesh quality and repeatability.

Batch Meshing

The Altair BatchMesher™ in HyperMesh is the fastest way to automatically generate high-quality finite element meshes for large assemblies. It is available as a standalone application or directly within Altair HyperMesh.

By minimizing manual meshing tasks, this automeshing 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.

Industry Specific Meshing

HyperMesh provides a variety of meshing algorithms for different industries and verticals, such as acoustic cavity meshing and mesh coarsening for NVH applications, and shrink wrap meshing or SPH meshing. HyperMesh also offers a highly-competitive suite of tools for CFD meshing.

CAD Interoperability

HyperMesh includes direct readers to popular native CAD file formats. Moreover, HyperMesh has robust tools to clean-up imported CAD geometry that contain surfaces with gaps, overlaps and misalignments which hinder high-quality mesh generation.

By eliminating misalignments and holes, and suppressing the boundaries between adjacent surfaces, users can mesh across larger, more logical regions of the model.

This significantly increases meshing speed and quality. Boundary conditions can also be applied to these surfaces for future mapping to underlying element data.
