ATA Engineering Announces the Release of Attune v2.2.0

Enhancements include automated node mapping, a pushback tool for more efficient design, and support for expanded design properties

SAN DIEGO, Calif., November 7, 2016 — ATA is proud to announce the release of version 2.2.0 of Attune. Attune is a highly automated test-analysis correlation and model updating software tool used by engineers who want to tune their finite element models quickly. This release incorporates a number of new features and enhancements, some of which are discussed below.

Notable Upgrades:

Easy automated node mapping to define USET

Automated node mapping capabilities for DOF set creation save you effort and avoid the potential for error. A new capability for comparing test and analysis DOF lets you hand off the task of creating a DOF set for reducing the mass matrix by automatically creating Nastran USET cards ready to include in your bulk data.

Pushback for more efficient design

Attune’s new pushback tool offers a convenient way to reduce inefficient design changes while preserving gains when using a genetic algorithm. Using a genetic algorithm is often the better choice for design optimization, but it does not always arrive at the most efficient option. Attune has added a pushback capability that lets you hold on to performance gains while walking back unnecessary changes to other aspects of the design.

Support for expanded design properties

An expanded list of design properties can now be defined and tuned with Attune’s powerful optimization capabilities. Attune contains a powerful GUI-driven capability to create design properties and variables for you and use these to create a Nastran optimization input deck. This capability now encompasses even more of the design properties you want to adjust, allowing you to tune more parts of your Nastran model.

Many other useful enhancements

  • Efficiently create design variables for an entire category of properties at a time.
  • Read test frequencies from .ash and .op2 files for frequency-only correlation.
  • Easily define design variables by element ID—just copy and paste element IDs into the Attune GUI.
  • Use overlapping Nastran property IDs for properties of different types.
