“…Fluid-Structure Interaction (FSI) problems arise in many scientific and engineering applications including, to name only a few, aircraft aeroelasticity 1,2,3 , parachute inflation dynamics 4,5,6 , hemodynamics 7,8,9 , and lithotripsy 10,11 . Besides the development of mathematical models, seamless integration of observation data with these models starts to play a significant role to improve the prediction and quantify uncertainty for FSI, for example, calibration of hemodynamic model parameters to match patient data 12,13,9 and structural damage detection using sensor data and a digital twin 14,15,16 .…”
