Fluid-Structure-Interaction (FSI)

These days, fluid–structure interaction plays a major role in engineering applications such as aircraft, buildings and energy generation. Failing to consider the effects of oscillatory interactions can be catastrophic, especially in structures comprising materials susceptible to fatigue. An Example is the structural collapse of the Tacoma Narrows Bridge in 1940.

Due to numerical simulation the real behavior of a component or flow can be reflected exemplary. Useful methods are the Finite-Volume Method (FVM) or Finite-Element Method (FEM). Both methods are based on solving partial differential equations.

The following movie shows the interaction of a streaming tube and his material. In each time step the vibration of the tube is visible.
