Kurzbeschreibung (Abstract)

The advantages of an unsteady implicit partitioned Fluid-Structure Interaction Scheme are; especially for large time step sizes; accompanied by a high number of inner iterations needed. This work investigates the use of extrapolation techniques in between time steps to obtain a smaller number of inner iterations. In contrast to previous works not only the structural displacement but also the fluid field variables are considered for extrapolation. The different extrapolation approaches are compared within a numerical benchmark.
