Workpackage 5 - Multiphysics modelling – from model to advanced simulations

Dernière mise à jour :

The factory of the future will rely on numerical technologies that should be able to design and manufacture innovative, complex, and optimized products, in terms of their properties, and be flexible and responsive to meet the various expectations. These challenges will require optimized experiments, data usage, and most importantly, virtual manufacturing processes that may replace tedious and costly legacy experimental campaigns. The two next topics support this objective.

Advanced multiphysics and multiscale numerical modelling. Most of the applications involve multiphysics and multiscale modelling approaches. Peculiar phenomena at the basis of some processes are still not well identified and / or modelled. Therefore, new modelling approaches are necessary and need to be adapted to the scale of observation / simulation in order to better characterize the properties of materials, their responses to conditions of use, and to control their manufacturing processes. The involved scale ranges from microscopic interfaces to macroscopic phenomena.

Advanced simulations. They will represent complex physical phenomena from the micro scale even up to the manufacturing processes scale. They will be based on high performance computing as well as up-scaling techniques. Moreover, in order to deal with some engineering problems, there is a need of reduced-order modelling and optimization techniques since computational resources are limited. These methods find their natural place in the design of hybrid and real time digital manufacturing twins.

The main contribution will be to develop numerical tools, repositories of skills and expertise, necessary to reach the long-term goals. These tools claim to be general, transversal, performant, easy to use, with state-of-the-art models and numerical methods, associated with computational strategies for numerical solutions of derived mathematical models, and of great interest for the different scientific communities involved in the project.
