Efficient approaches for fluid structure interaction with fully enclosed incompressible flow domainsKüttler, U. (author), Förster, C. (author), Wall, W.A. (author)Many popular partitioned approaches to fluid-structure interaction (FSI) problems fail to work for an interesting subset of problems if highly deformable structures are interacting with incompressible flows. This is particularly true for coupling approaches based on Dirichlet-Neumann substructuring, both for weak and strong coupling schemes. The...conference paper 2006

Förster, C. (author), Wall, W.A. (author), Ramm, E. (author)The artificial added mass effect inherent in sequentially staggered coupling schemes is investigated by means of a fluid-structure interaction problem. A discrete representation of a simplified added mass operator in terms of the participating coefficient matrices is given and instability conditions are evaluated for different temporal...conference paper 2006
