What Is 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.
