Baker Hughes Drills 60% off Product Development Time Faced with the challenge of validating an advanced oil well liner, Altair used simulation to reduce prototypes required, improve system capability, and accelerate product development time. Read the Baker Hughes Case Study
HyperStudy enables users to explore, understand and improve their designs using methods such as design-of-experiments, response surface modelling and optimization. Results from these studies can be easily analyzed and interpreted using HyperStudy’s advanced post-processing and data mining capabilities. HyperStudy’s intuitive user interface combined with its seamless integration to HyperWorks for direct model parameterization and CAE result readers simplifies the study setup.

Perform Trade-off Studies

HyperStudy’s fit capability allows users to create response surface models. These efficient surrogates can then be used to perform trade-off studies. They can also be exported as spreadsheets for field engineers’ use.

Reduce Development Time and Costs

HyperStudy helps engineers reduce trial-and-error iterations and hence helps to reduce both the design development and testing time.

Capabilities

Design of Experiments

Design of Experiments (DOE) methods in HyperStudy include:

  • Full factorial
  • Plackett-Burman
  • Central composite design
  • Modified Extensible Lattice Sequence (MELS)
  • Hammersley
  • D-Optimal
  • Fractional factorial

  • Box-Behnken
  • Latin hypercube
  • User defined and direct input of external run-matrix
  • Taguchi

The study matrix can consist of continuous or discrete variables that can be either controlled or uncontrolled. DOE studies can be performed using exact simulation or the fit model.

Response Surface Method (Fit)

Available response surface methods are:

  • Least squares regression
  • HyperKriging
  • Moving least squares
  • Radial basis functions.

Response surfaces can be used for performing trade-off, DOE, optimization and stochastic studies.

Optimization

HyperStudy’s comprehensive optimization methods solve different types of design problems including multi-objective and reliability/robustness based design optimization. These methods are:

  • Adaptive response surface method (ARSM)
  • Sequential quadratic programming
  • Genetic algorithm
  • System Reliability Optimization (SRO)
  • Sequential optimization and reliability analyses (SORA)
  • Single loop approach
  • Method of Feasible Directions (MFD)
  • Global response surface method (GRSM)
  • Multi-objective genetic algorithm
  • ARSM based SORA
  • User-defined optimizer

Optimization studies can be performed using either exact simulation or fit model. In addition, HyperStudy provides an API to incorporate external optimization algorithms.

Stochastic

The stochastic approach in HyperStudy allows engineers to assess reliability and robustness of designs and provide qualitative guidance to improve and optimize based on these assessments. HyperStudy sampling methods are:

  • Simple random
  • Hammersley
  • Latin hypercube
  • Modified Extensible Lattice Sequence (MELS)

Stochastic studies can be performed using either exact simulation or the fit model.

Post-Processing and Data Mining

HyperStudy helps engineers to gain a deeper understanding of a design through extensive post-processing and data-mining capabilities. This significantly simplifies the task of studying, sorting and analyzing results. Study results can be post-processed as statistical data, correlation matrices, scatter plots, box plot, interaction effect plots, histograms, and parallel coordinates among others. Furthermore, HyperStudy guides the user in the selection of post processing methods to use based on the design objectives.
