Fluid structure interaction (FSI) plays a critical role in healthcare by involving the simulation of the interaction between fluid and structure. The fluid represents physiological fluids such as blood or cerebrospinal fluid, while the structure refers to biological tissues or medical devices. FSI simulations enable the prediction of how fluid flow affects the behavior of structures, and vice versa, leading to improved understanding and treatment of various medical conditions. Through computational modeling and experimental techniques, researchers and clinicians can analyze the impact of FSI on phenomena such as blood flow in arteries, drug delivery in the body, and the interaction of medical implants with surrounding tissues, facilitating the development of personalized treatments and optimizing healthcare outcomes.
