Development of reduced-order models methods for the simulation of industrial problems

The industrial uses of numerical simulation continue to diversify: this technique benefits from constant innovation, resulting from the collaborative work of academic and industrial engineers and researchers. The present feedback, which provides an example, concerns the development of numerical methods based on reduced-order models and integrated into calculation codes that can be used by industrial engineers. The applications targeted – vibro-acoustics and hydrodynamics – mainly concern problems of interest to the naval sector, but also relate to physics encountered in many other sectors, such as transport or energy, etc.

The development of these methods was part of a research program undertaken over several years by a major international shipbuilder, in collaboration with academic researchers with expertise in physical modeling and numerical simulation. It has enabled new numerical approaches to be developed, opening the way to optimization and improvement of structures subjected to a variety of mechanical stresses (vibratory, hydrodynamic, etc.), and to make these techniques accessible to design engineers.
