Acoustics module

Designed for those who work with devices that generate, measure and use acoustic waves, the COMSOL product line now features an Acoustics module that is ideal for examining mechanical wave phenomena in structures and fluids. Users can easily model wave propagation in solids and stationary fluids, as well as study aeroacoustics in moving fields. The module provides a variety of application modes that offer tailored user interfaces loaded with predefined settings. Users can create or import a geometry, fine-tune the physics settings, and solve the problem. To help users get a head start on developing their models, and to learn tips and tricks to make their modeling more effective, the module comes with a Model Library that contains more than a dozen entries. Each comes with a detailed theoretical discussion followed by step-by-step instructions, although users can instead simply load a supplied model file. One example examines the open-pipe problem, which is a classic benchmark dealing with resonances, while another studies reflection of forward-propagating modes in jet engine intake. Results are compared to published simulations and semi-analytical solutions.
