Linear Duct with a Movable Rigid Wall

In this example problem, the sound field inside a linear duct is studied. The wall on the right hand side is movable and is supported by a spring and damper. In addition, the right wall acoustically rigid. Vibration excitation is provided by shaking the left wall. Here, we describe the steps in preparing the model, and compare the solution from Coustyx with the exact analytical solution. We came across this example in a paper by Suzuki [1] and created a Coustyx model to try it out. The derivation of the analytical solution based on structure mobility, although straightforward is new.
