Attune

Attune is a stand-alone highly automated test-analysis correlation and model updating software tool which combines more than 30 years of experience in this field into a user-friendly, flexible, MATLAB®-based toolkit. By automating the correlation process and providing a suite of leading edge optimization tools, Attune provides the user with a powerful, efficient method of generating accurate test-verified finite element models. Attune allows users to:

  • Carry out correlation and model updating through a user-friendly Graphical User Interface (GUI).
  • Correlate test and analysis data based on modally reduced matrices.
  • Simultaneously optimize the design of multiple configurations.
  • Correlate frequency, cross-orthogonality, and MAC.
  • Correlate frequencies without the associated shape data.
  • Use advanced history tracking to investigate the design space and reevaluate designs based on new criteria.
  • Export ready-to-run updated NASTRAN bulk data and ABAQUS input decks of optimized analysis models.
  • Customize the objective function or use a user-developed optimization algorithm.
  • Automatically document model updating process.
