2.1 – Topology optimization of stationary fluid-structure interaction problems including large displacements [1]
The inclusion of large displacements into the optimization problem allows solutions closer to a realistic design since the structural systems demands nonlinear responses in real working conditions. To illustrate this concept, the classical “the wall” optimization problem including nonlinear structural responses is presented below.

2.2 – Topology optimization of stationary turbulent fluid-structure interaction problems via sequential integer linear programming and smooth explicit boundaries [2]
Most of the works in TO-FSI literature consider laminar flow, which is far from practical applications. In this context, the TOBS-GT method integrated with a smoothing technique based on a phase field function is proposed to solve the FSI turbulent problem. Here, the classical “the wall” example subjected to turbulent flow (Re = 5,000) modeling using the k-ω turbulence model is presented.
