Altair HyperMesh is the industry-standard environment for finite element pre-processing — the tool most automotive and aerospace teams reach for when a model is too large or too complex for a CAD-embedded mesher. It turns messy CAD into solver-ready meshes fast, and is solver-neutral: the same model can be written out for OptiStruct, Nastran, Abaqus, LS-DYNA, Radioss or Ansys.
Altair is now part of Siemens, and DDSPLM delivers the combined Siemens Simcenter and Altair simulation portfolio across India — with local licensing, training and engineering support.
What HyperMesh does well
- Geometry cleanup & mid-surfacing — automated de-featuring, gap closing and shell extraction for thin-walled structures.
- High-quality meshing — shell, solid (tetra and hexa), 1D and CFD surface meshes with tight control over element quality criteria.
- Batch meshing — the BatchMesher automates cleanup and meshing of large part libraries to consistent, repeatable quality standards.
- Connectors — realistic representation of spot welds, bolts, adhesives and seam welds that update automatically as the mesh changes.
- Morphing — reshape an existing mesh (HyperMorph) to study design variants without going back to CAD.
- Assembly & model management — handle million-element assemblies, includes, and sub-system organisation.
Where it fits
HyperMesh is the meshing backbone for crash, NVH, durability and structural analysis — feeding solvers such as OptiStruct and Radioss in the wider HyperWorks suite. For early-stage studies on full CAD assemblies where meshing isn’t worth the effort, pair it with Altair SimSolid.
AI-accelerated meshing
HyperMesh now includes AI-assisted meshing capabilities that learn from historical mesh patterns to automate geometry cleanup and element-quality improvement. For large automotive BIW (body-in-white) assemblies with hundreds of parts, AI-assisted batch meshing reduces manual intervention and delivers consistent mesh quality at scale.
Industry applications
- Automotive — full-vehicle crash (frontal, side, rear, pedestrian), NVH (noise-vibration-harshness), durability (fatigue, proving-ground loads), and powertrain thermal-structural coupling. HyperMesh handles BIW models with millions of elements routinely.
- Aerospace — airframe primary and secondary structure meshing, composite layup definition, landing gear and engine-mount load-path analysis.
- Heavy equipment — excavator booms, crane structures, pressure vessels and large welded fabrications.
- Electronics — PCB-level drop test and vibration model setup.
HyperMesh in the Altair HyperWorks ecosystem
HyperMesh is the pre-processing front end for the full HyperWorks suite — feeding models to OptiStruct (structural optimisation), Radioss (crash and impact), MotionSolve (multi-body dynamics) and AcuSolve (CFD). For rapid early-stage analysis without meshing, pair it with Altair SimSolid.
Licensing
HyperMesh is licensed through Altair Units — a token-based model that gives access to the entire HyperWorks suite. Contact DDSPLM for a deployment plan that fits your team size.
