Fluid–structure interaction (FSI) refers to the complex interplay between a fluid (liquid or gas) and a solid structure when both are in motion or when forces are applied to them. FSI is a critical area of study in various fields of engineering and physics, as it affects the performance, stability, and durability of structures like bridges, aircraft, pipelines, and biological systems, among others.
