Development of finite element formulations for fluid-structure interaction modelling

The maturing of a scientific calculation method, from its mathematical formalization to its practical application, via its numerical implementation, is an innovation challenge for industrial players in numerical simulation (numerical modeling researchers, calculation code publishers, simulation tool users).

Completing the entire maturity cycle and making new computing functionalities available to a community of users requires working with all the players involved at the various key stages (formalization, validation, implementation, marketing).

We provide feedback on an industrial R&D project aimed at integrating new computational functionalities for mechanical problems involving fluid/structure interaction modeling into a general-purpose finite element calculation code. Carried out following doctoral work, the project involved a numerical solutions publisher and an industrial user of the calculation code. It led to the enhancement of the computational code's offering, and enabled various applications of these functionalities to problems of interest to the shipbuilding and nuclear industries.
