Fluid Structure Interaction – FSI

FSI - Fluid Structure Interaction

Fluid Structure Interaction (FSI) combines the description of a flow with the interaction of a solid. The methods CFD and FEA are applied simultaneously to adequately describe complex systems.

Examples include the contraction of blood vessels and their influence on blood flow, the formation of a thrombus in devices through which blood flows, or the displacement of fluid in a pump.
