Abstract: SUMMARYAn explicit-explicit staggered time-integration algorithm and an implicit-explicit counterpart are presented for the solution of non-linear transient fluid-structure interaction problems in the Arbitrary LagrangianEulerian (ALE) setting. In the explicit-explicit case where the usually desirable simultaneous updating of the fluid and structural states is both natural and trivial, staggering is shown to improve numerical stability. Using rigorous ALE extensions of the two-stage explicit Runge-Kutta and th… Show more

“…Therefore, if the flow field is approximated by an explicit time-integration technique, the upper bound on the time step imposed by the stability of the coupling algorithm does not in general imply an essential degradation of the computational efficiency of the coupled problem relative to the flow problem separately, irrespective of the speed of sound. Moreover, conversely, the timestep restriction imposed by an explicit time-integration scheme for the fluid subproblem typically ensures that a staggered method can be used to account for the coupling between the fluid and the structure; see also [9].…”

“…The modified continuity equation (7) introduces an artificial compressibility in the spirit of [11], but with two important differences. First, it is restricted to the interface and, second, it is weakly consistent with the original continuous problem.…”

“…Specific examples include the parametric identification of an F-16 Block-40 fighter aircraft in clean wing configuration and subsonic, transonic, and supersonic airstreams Farhat et al, 2003); the aeroelastic analysis of an F/A-18 5.6 Hz limit cycle oscillation configuration; the flutter clearance of the laminar flow wing of a supersonic business jet concept; and the aeroelastic tailoring of a Formula 1 car. Examples of incompressible FSI problems include the study of intense implosive collapses of gas-filled underwater structures and their effects on nearby structures (Farhat et al, 2010).…”
