CS simulation group engineers and experts design, analyze, develop, verify and validate for aeronautical customers whenever it is possible with mathematical models and associated computational methods for high performance simulation of multi-disciplinary engineering problems.

• aero-structures and engine components specific design calculations and justification studies: statics, dynamics of metallic and composite primary structures.
• aero-structures and engine components non-specific design advanced calculations studies: aerodynamics, fluid-structure interaction (aero elasticity…), electromagnetism, thermal analysis, aero therm dynamics…
• development of computational methods for the high performance simulation of multidisciplinary engineering problems.

CS continuously specializes in distributed computing and massively parallel processing, with a specialized activity fully dedicated to software optimization (recent example: the optimization of the ONERA aerodynamics software elsA for AIRBUS).
Current CS research emphasis is on reduced-order modeling, multi-scale approximation methods, global multidisciplinary optimization methods, imaging, uncertainty quantification and various large-scale applications in aerospace (like large-scale aerodynamics and aero acoustics simulations).

Recent efforts have focused on and continue to address new process strategic disciplines for aeronautical industry like:

• Simulation Lifecycle Management (SLM)
• Verification & Validation methods
• CAD-CAE links
• Virtual testing

With the Airbus Virtual Aircraft Project, CS is particularly involved in the following disciplines and tasks:
VIRTUAL AIRCRAFT: establishing the Virtual Aircraft Functional Architecture (VAFA)
The Virtual aircraft is a mean to simulate a/c assembly (physical design) and a/c operations (functional design) of the “to-be” aircraft before its actual integration in order to deliver in a shortest time a competitive, operable, operational and “good for certification” and “production defi nition” file.
CAD-CAE LINKS: setting virtual aircraft strategic End-to-End processes
CCL objective is to reduce modeling lead time and labour intensive cost of the modeling process.
VIRTUAL TESTING: setting Virtual Testing Generic processes
To develop a set of modeling & simulation means to demonstrate:
• the design is compliant with certifi cation requirements;
• also used for early assessment of the design.
