The artificial added mass effect in sequential staggered fluid-structure interaction algorithms

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...

Partitioned strategies for optimization in FSI

In this paper the possibility of the optimization of coupled problems in partitioned approaches is discussed. As a special focus, surface coupled problems of fluid-structure interaction are considered. Well established methods of optimization are analyzed for usage in the context of coupled problems and in particular for a solution through...
