TL;DR: This paper considers the realistic situation where the fluid and structure subproblems have different resolution requirements and their computational domains have non-matching discrete interfaces, and addresses the proper discretization of the governing interface boundary conditions.

TL;DR: This paper presents a dual–primal formulation of the FETI‐2 concept that eliminates the need for that second set of Lagrange multipliers, and unifies all previously developed one‐level and two‐level FETi algorithms into a single dual‐primal FetI‐DP method.

TL;DR: In this paper, the authors proposed a method to control the arbitrary motion of two-dimensional dynamic unstructured fluid grids with additional torsional springs, which can be designed to prevent the interpenetration of neighboring triangles.

TL;DR: This paper proposes two alternative serial and parallel staggered algorithms for the solution of coupled transient aeroelastic problems, and demonstrates their superior accuracy and computational efficiency with the flutter analysis of the AGARD Wing 445.6.

TL;DR: In this paper, a unified theory for deriving Geometric conservation laws (GCLs) for flow problems with moving boundaries is presented, and the impact of these constraints on the solution of coupled aeroelastic problems, and highlight the importance of the GCLs with an illustration of their effect on the computation of a flat panel in transonic flow.
