Traditional software offerings operate usage ‘token’ systems which stack applications. The HyperWorks software products are accessed via a patented licensing system which allows multiple applications to be opened on the
desktop and the ‘tokens’ levelled to the maximum token value product.
The HyperWorks licensing system delivers significant cost savings compared against the industry standard stacking systems. In addition, by levelling the tokens to the maximum product value, the company only pays for
incremental usage.

ApproximationsApproximations are meta-models that are used to replace computationally intensive simulations. They are also used to smooth noisy functions to enable optimization algorithms to work more effectively on any given design problem. Approximations can be used in both optimization and stochastic studies.
Altair® HyperStudy® is solver-neutral study, design and optimization software that streamlines exploring and optimizing the performance and robustness of designs. HyperStudy is a tool of choice for the designer and engineer who are tasked with improving designs, running what-if scenarios, correlating test data, optimizing multidisciplinary design problems or assessing design reliability and robustness.

HyperStudy’s approximation module allowscreation of different approximations fordifferent responses. Available approximationmethods are least squares regression,moving least squares and HyperKriging.
Multidisciplinary, Reliability, andRobustness OptimizationHyperStudy offers multidisciplinary study capabilities as well as reliability and robustness optimization. Through multi-disciplinary design studies, engineers can improve the overall design performance. If variations in design and operating environments are critical to design quality, reliability and robustness optimization can be used reduce the sensitivity of designs to these variations.
HyperStudy contains a comprehensive suite of optimization algorithms that include:• Altair’s proprietary efficient-optimization algorithm adaptive response surface method (ARSM)• Sequential quadratic programming (SQP)• Method of feasible directions (MFD)• Genetic algorithm (GA)• Sequential optimization and reliability
analyses (SORA).• User-defined optimization algorithms
(through included API)
Stochastic StudiesThe stochastic study capability in HyperStudyallows engineers to assess reliabilityand robustness of designs and providequalitative guidance to improve and optimize the design based on these assessments.
HyperStudy sampling methods include:• Simple Random• Latin Hypercube• Hammersley • Statistical distribution functions (Normal,
Uniform, Triangular, Weibull and Exponential)
Stochastic studies can be performed using either the exact simulation or approximation model.
Post-Processing and Data MiningHyperStudy helps engineers to gain a deeperunderstanding of a design through extensivepost-processing and data-mining capabilities.This significantly simplifies the task ofstudying, sorting and analyzing results.
Study results can be post-processed as:• Statistical data• Correlation matrices• Scatter plots• Interaction effect plots• Histograms• Snake view plots
In addition, HyperStudy provides a series of data-mining tools, such as principal components analysis and clustering analysis.
Evaluation and RatingA large database for signal analyses andcomparison functions allows engineers toperform data correlations. These correlations can then be evaluated and rated based on user-defined criteria.
Parameterization of Analysis ModelsHyperStudy's direct integration with AltairHyperMesh and Altair MotionView providesthe capability to directly parameterize finite-element, multi-body and fluid-dynamics-solver input data for CAE solvers, thus making the study parameterization process easy and efficient. For other solvers, HyperStudy employs a streamlined parameterization method for preparing an input deck using a built-in text and numeric processor.
Shape Parameter Definition UsingMorphing TechnologyShape changes can be easily createdon complex finite-element modelsusing the powerful morphing technologyin HyperMesh. These morphed shapescan be saved as HyperStudy shapeparameters and examined to evaluatetheir effect on design performance.
Direct Interfaces to Popular SolversTo facilitate streamlining the study processwithout additional data filtering andtranslation steps, HyperStudy directlyreads the plot and animation data ofmany solvers, including:
• ABAQUS• Adams• ANSYS• DADS• Excel• Fluent• LS-DYNA• MADYMO
• MARC• Matlab/Simulink• MotionSolve• NASTRAN• OptiStruct• PAMCRASH• RADIOSS• StarCD
