Aerospace industry migration to nonlinear finite element analysis
Simulation in the aerospace industry is currently in a transition period. In the 70s, engineers used design guide books to develop products. FEA started with simple “stick” models. “Stick” models usually contained beam elements and a few shell elements and were a few thousand degrees of freedom (dof).
In the next decade, companies continued to use simple, linear FEA models, but the number of degrees of freedom grew to 1 million dof. These larger models still used primarily shell elements and were mostly linear models.
Today, we are seeing a transition realistic FEA. Realistic FEA includes multiphysics, the use of larger models (20 Mdof), and the inclusion of damage and fracture. The transition is being driven by new materials, weight and the request for better products.

Below you can find customer references for the aerospace industry.
Abaqus at Airbus Defense and Space -formerly known as Dutch Space (the Netherlands)
The engineers were able to create a highly accurate simulation of the thermal protection system, creating results that were within 3-5% accuracy. Program costs were reduced by the elimination of full-scale thermo-mechanical tests, and development timeframes were reduced.
Isight at Thales Alenia Space Italia (Italy)
The solution enabled aerospace design engineers to build complex, multi-step workflows and automate the optimization and verification of their designs.
The ability to integrate multiple simulations using extensive real-world flight condition measurements resulted in the elimination of conservative design assumptions, while also saving development time and encouraging departmental design collaboration.
Simpack at Max Planck Institute for Solar System Research (Germany)
Simpack helped the institute to land the Rosetta space probe on comet 67P/Churyumov–Gerasimenko.
HyperSizer at Bell Helicopter (US)
HyperSizer is used to design and analyze the Bell V280 helicopter fuselage. It is employed in a ‘design-by-analysis’ approach that successfully sized and analyzed the fuselage structure.
Vcollab at Kelly Space & Technology, Inc.
Michael J. Gallo, President and Chief Operating Officer stated: “I must say that I was extremely impressed with the capabilities of this product. I was able to work with virtually all of the program features which demonstrated to me that this product is exceptionally user-friendly.”
Our team is active in bird strike simulations, composite fracture and failure and other aerospace related simulations.
