Automated, user-friendly, test-analysis correlation and model-updating


  • Provides correlation based on modally reduced model matrices
  • Correlates frequency, cross-orthogonality, MAC, and FRF
  • Simultaneously optimizes multiple configurations
  • Includes Monte Carlo, gradient-based, and genetic algorithm optimizations
  • Offers an interface with Microsoft ® Excel for easy documentation
  • Compatible with Nastran and ABAQUS


Attune is an automated test-analysis correlation and model updating software tool which is user-friendly, flexible, and is based on MATLAB®. By automating the correlation process and providing a suite of leading-edge optimization tools, Attune provides a powerful and efficient method of generating accurate, test-verified, finite element models.

Attune is built entirely in the MATLAB environment and uses MATLAB for both computation and visualization. Typical end users are engineers seeking to improve the fidelity with which a finite element model matches experimental data.
