Specialists in Numerical Simulation and Test Engineering

Conventional, renewable and heavy industry energies: our teams work with the major players in these constantly evolving sectors for the production, management and storage of energy or the development of advanced industrial tools.

Nuclear

Nuclear projects are spread all over the world and face complex economic and technological challenges specific to this field, such as the reduction of additional costs during the design and construction phases, the optimisation of productivity, or the problem of dismantling plants and equipment.  This sector is subject to strict regulations, which are well understood and managed by our teams, whose actions are essentially directed towards reducing design time and optimising nuclear installations.

Oil & Gas

From extraction to the refining of petroleum products, our teams support manufacturers by developing complex virtual prototypes. They simulate new hydrocarbon extraction and production concepts in environments where physical testing is almost impossible (horizontal drilling, hydraulic fracturing, etc.). Our studies make it possible to optimise the production flows, the drilling processes and to limit the risks of explosion.

Renewable energy sources

From photovoltaic energy, to wind turbines and tidal power units, our simulation studies focus on highly innovative designs in complex environments where very strong natural constraints such as wind, sea currents or solar radiation reside. Our expertise in numerical simulation makes it possible to test the interactions between thermal, physical and communication constraints during the design phases, thereby improving the performance in terms of safety, reliability and energy efficiency.

Heavy industry

Mining, iron and steel or paper mills require expensive and more efficient means of production in terms of economic profitability and energy efficiency. We support manufacturers in the development of optimised production tools thanks to our automated modelling techniques for large structures for multi-physics issues.
