Splitting Schemes for Fluid/Thin-Walled Structure Interaction Using Unfitted Meshes

Poster at International Workshop on Numerical Methods and Applications in Fluid-Structure Interactions, Laboratoire Jean Kuntzmann, Grenoble, France
Poster presentation on splitting schemes for fluid and thin-walled structure interaction using unfitted meshes. The work extends explicit Robin-Neumann coupling to configurations where the structure is not matched by the fluid mesh, with the interface conditions enforced weakly through Nitsche’s method. This combines the efficiency of loosely coupled time-marching with the flexibility of unfitted discretizations, which avoid remeshing or deforming the fluid mesh as the structure moves.
