Attune

mathworkspartnerlogoAttune is a stand-alone highly automated test-analysis correlation and model updating software tool which combines nearly 40 years of experience in this field into a user-friendly, flexible, MATLABĀ®-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 model frequencies during the design phase (without test 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.
  • Easily create design variables using the GUI and create a Nastran optimization deck.
  • Automatically document model updating process.

Additional Information

Attuneā„¢ v2.2.2 is supported on Windows 7/8/10 and Linux platforms and requires MATLAB version 2015a or later. Attune is compatible with MSC.Nastran v2001 or later and all versions of UGS NX Nastran. Performing model updates on Nastran models with Attune requires Nastran Optimization and DMAP licenses. Attune is also compatible with Abaqus version 6.5 or later and Salinas version 4.19.3 or later. See the online user’s guide for more information. Attune Stand-Alone requires the MATLAB Runtime Libraries, version 9.1, and the Community Edition of ActiveState Perl to be installed.
