The animation illustrates a one-to-one comparison of the 2D buffeting response generated by a semi-analytical aerodynamic model and a CFD model, both of which are subjected to synthetic free-stream turbulence.

The animations show flutter and limit cycle oscillations of the Great Belt Bridge, simulated using the Vortex Method in 2D.

The animation shows flutter and limit cycle oscillations of the Great Belt Bridge, subjected to a sinusoidal vertical gust with the same frequency as the torsional frequency.

The animation shows a sinusoidal vertical gust simulated in CFD. The inflow particles are generated using a numerical Active Turbulence Generator.

The animation shows buffeting of the Great Belt Bridge, simulated using a Turbulent Pseudo-3D Vortex Method with synthetic random free-stream turbulence acting only on the deck. Six representative CFD planes are shown out of fifty considered along the deck.
