TL;DR: In this paper, a high-order coupled fluid-structure solver based on fully coupled Navier-Stokes and nonlinear structural dynamic equations has been employed to study the self-induced flapping dynamics of an inverted flexible foil in a uniform flow.

TL;DR: In this article, a stable partitioned iterative scheme for solving fluid-body interaction problems at low structure-to-fluid mass ratio is presented, which relies on the so-called nonlinear interface force correction based on Aitken's extrapolation process to stabilize the coupled partitioned system employing an arbitrary Lagrangian-Eulerian finite element framework.

TL;DR: It is shown theoretically that the accurate transfer preserves the stability of the coupled system while maintaining the energy conservation over a reference interface, and simple analytical error functions are introduced which correlate well with the numerical errors of the load transfer schemes.

TL;DR: The proposed CNN-based approximation procedure has a profound impact on the parametric design of bluff bodies and the feedback control of separated flows.

TL;DR: This work presents a detailed comparative study of three conservative schemes used to transfer interface loads in fluid–solid interaction simulations involving non-matching meshes, and introduces a grid mismatching function which correlates well with the errors of the traditional load transfer schemes.
