Coupled problem with elastodynamics and acoustics
We solve linear elastodynamics inside the stanford bunny. Outside the object we eliminate one term and obtain linear acoustics. For details, see

Sound propagation in windy condition
Sound propagation in windy condition
Sound propagation problems are important when deciding locations of wind turbines. We solve large wave problems by converting 3-dimensional problem into 2-dimensional simulation. The wind is approximated with variable wave velocity. Our aim in the future is to employ space-time meshing for more realistic modeling of wind.
Fig: Sound propagation in headwind, calm and tailwind. The wave turns up in headwind, because wind speed is slower near the ground.
