Altair Engineering has released an upgraded technology package that brings together all the tools that engineers require for the complete design and analysis of vehicle powertrains.

According to the company, Simlab 12.0, a software tool created specifically as a pre-processor for detailed computer models of complex powertrains, has been released as part of Hyperworks 12.0, Altair’s suite of computer-aided engineering software. Because it now is integrated into Hyperworks, Simlab can be run with the same Hyperworks units that designers and engineers use for all the other Hyperworks simulation tools, making it more accessible and cost-efficient than before.

The automotive industry can use Simlab for powertrain modelling and setup, along with Optistruct 12.0 for powertrain analysis and optimisation.

These tools are supplemented by Hyperworks systems such as Hypermesh for shell and simple solid meshing and setup; Morph Mesh for rapid design iteration and optimisation; Acusolve for thermal and computational fluid dynamics analysis (CFD); the Radioss solver for crash impact; and Hyperview for viewing results contours, animations and plotting, as well as advanced noise-vibration-harshness (NVH) diagnostics.

Software in detail


  • Simlab’s role in simulation preparation includes feature-based solid meshing for structures such as the engine crankcase and cylinder head and the setup of simulation loads and boundary conditions.
  • With Simlab 12.0, meshes require no manual clean-up — perfectly clean meshes are generated automatically.
  • Overall, Simlab 12.0 can provide a 30 per cent improvement in meshing and substantial improvements in setting up large finite-element models.
  • Simlab brings to all Altair powertrain customers a comprehensive solution for the meshing of complex solid models.
  • The software can be used for some very powertrain-specific post-processing use cases, such as the analysis of cylinder bore distortion from heat and pressure and results mapping for CFD and thermal analysis.


  • Optistruct’s powerful solver is used for structural design optimisation
  • It helps the industry develop lightweight and structurally efficient designs by analysing and optimising strength, durability and NVH performance.
  • Optistruct can be used to apply advanced numerical optimisation technologies to improve the design.
  • The software has been advanced with a number of specific features, including gasket elements, an accurate and robust contact formulation, plasticity enhancements and a thermal analysis sequence.
