Acoustic-Structure Interaction
Liquid or gas acoustics coupled to structural objects such as membranes, plates or solids are important applications in many engineering fields. Some application examples include: loudspeakers, acoustic sensors, nondestructive impedance testing, medical ultrasound diagnostics of the human body.This model is a general demonstration of an acoustic fluid phenomenon in 3D that is coupled to a solid object. The walls of the solid object are impacted by the acoustic pressure. The frequency response from the solid is calculated, which is then fed back to the acoustics domain so that the wave pattern can be analyzed. As such, the model becomes a good example of a scattering problem.
