Abstract
In this contribution, we revisit adjoint formulations for stationary and nonstationary spacetime fluid-structure interaction. The adjoints serve for two purposes: goal-oriented a posteriori error estimation with the dual-weighted residual method and gradient-based numerical optimization. Our developments are substantiated with comments on numerical simulations in some other published studies.
