An enriched finite element approach for prescribed motions of thin immersed structures in a fluid

Résumé

An Eulerian-Lagrangian fluid-structure coupling approach is presented. The method is dedicated when several thin structures are immersed in a fluid domain. Moreover, the structures may have large displacements. The finite element method is used for the space discretization. A fractional time scheme is used for time integration. The main point of the method is that the fluid mesh is fixed and is completely independent of the structure positions. In order to take into account the interface inside the fluid elements, new functions are added in the velocity and pressure fluid fields by using the extended finite element method X-FEM.
