Numerical methods for fluid, structure and interactions problems

14 nov. 2022, 12:00 → 18 nov. 2022, 14:00 Europe/Paris

Amphithéâtre Schwartz (IMT)

Aims and scope:

Fluid-structure interactions, although well studied, still present many difficulties and mathematical challenges. Techniques greatly differ depending on the nature of the problem and whether one uses the fluid or structure part of the problem. This workshop will feature altogether recent numerical methods for fluid and structure models, but also for fluid-structure interactions, through applications in aerodynamics and medicine. Part of the workshop will be devoted to practical implementations on a computer.

This workshop is part of the thematic semester Modelling, numerical analysis and scientific computing in PDEs organized by the Labex CIMI.
