4 What does Wiki have to say Fluid structure interaction (FSI) とは内部または周囲の流体の流れを持ついくつかの可動または変形可能な構造の相互作用であるたとえば紙が舞い落ちる現象, 旗やこいのぼりが風にはためく現象, あるいは心臓が拍動し血液が流入出するといった現象など, 流体力が構造の変形をもたらし, 同時に変位変形する構造が流れ場に影響を及ぼすことを考慮しなけばならない力学問題のことである My addition: FSI includes applications where the surface of the fluid changes as it flows in, around or over a solid. This can include or filling, empting, mixing or sloshing

between buildings, the amount of deflection caused by wind load, thermal efficiency,

9 Competitive Advantage Aluminum Curtain Wall Systems Inc. Before we create a physical prototype, we can test things such as wind loading between buildings, the amount of deflection caused by wind load, thermal efficiency, and convection transmission. Autodesk Simulation software buys us time and confidence. Tim Bourdois Systems Engineer
