Collaborative Research Projects

SARAH is concerned with establishing novel holistic, simulation-based approaches to the analysis of aircraft ditching. It is build up from a consortium of experts from OEM industries, experienced suppliers of simulation technologies, established research institutions and representatives of the certification authorities. Results of SARAH are expected to support a performance-based regulation and certification for next generation aircraft and helicopter and to enhance the safe air transport as well as to foster the trustworthiness of aviation services.

HydroSafeTire is about sustainable mobility of goods and people: fuel consumption reduction for light vehicles and trucks, reduction of noise pollution, reduction of environmental impact (optimization of raw material utilization) while maintaining security performances of tires.

PASC SPH-EXA project addresses the challenge of making SPH-based simulation codes scalable to future Exascale computing systems. The main objective is to have a scalable and fault tolerant SPH kernel, developed into a mini-app and co-designed by both astrophysics and CFD experts.

OPTIROUTES program aims at reducing ship consumption by integrating environmental aspects (wind, sea currents, heave) within the design and construction phase as well as exploitation.

HYSMER project’s purpose is to develop a precise and efficient software suite able to simulate the behavior of a marine structure at sea.

The Living Heart Project is uniting leading cardiovascular researchers, educators, medical device developers, regulatory agencies, and practicing cardiologists on a shared mission to develop and validate highly accurate personalized digital human heart models.
