The deal covers all divisions of the aerospace giant, best known for its Airbus commercial airliners.

Global aerospace firm EADS, the parent company of Airbus, has struck a  “master agreement” deal with  engineering simulation and analysis software vendor Ansys.  EADS uses Ansys technology across all its divisions for structural mechanics, fluid dynamics and electromagnetics simulation.

The very fact that Ansys is announcing this particular deal means it is “material” to its business—meaning  the deal will generate enough revenue to impact corporate results. Ansys did not disclose the size of the deal except to say it covers all EADS divisions.

Ongoing use of Ansys software at EADS will be to perform, among other applications, virtual testing of composite materials, aerodynamics optimization, thermal management, and signal integrity validation on products ranging from aircraft to helicopters to space launchers to defense systems. EADS has been an Ansys customer for nearly 15 years; “This agreement strengthens our relationship,” said Robert Harwood, aerospace and defense industry director, Ansys.
