#Ease acoustic simulation software software

Applications include HVAC systems, large piping systems, and musical instruments such as organ pipes.Д®lectroacoustics: Speakers and Microphones The Acoustics Module can also be used to model pipe acoustics, computing the acoustic pressure and velocity in flexible pipe systems. Further, you are able to use radiation or Floquet periodic boundary conditions to model open or periodic boundaries.

Sources like prescribed acceleration, velocity, displacement, or pressure can be applied on exterior or interior boundaries. You can use ports to excite or absorb acoustic waves at the inlet and outlet of waveguides using multimode expansion. For instance, you can add a boundary condition for a wall or an impedance condition for a porous layer. There are many options to account for boundaries in acoustics models. In the time domain, time implicit (FEM) as well as time explicit (dG-FEM) formulations are available. In the frequency domain, both FEM and BEM are available, as well as hybrid FEMвЂ“BEM. Simulations run in the frequency domain employ the Helmholtz equation, whereas in the time domain, the classical scalar wave equation is used. You can model pressure acoustics effects, such as the scattering, diffraction, emission, radiation, and transmission of sound. Pressure acoustics is the most common use of the Acoustics Module. In addition to the finite element method (FEM), the Acoustics Module features the boundary element method (BEM), the discontinuous Galerkin finite element method (dG-FEM), and ray tracing. The multiphysics environment is extended further with several numerical methods. The Acoustics Module also includes many specialized formulations and material models, like thermoviscous acoustics, used in miniature transducers and mobile devices, or Biot's equations, used for modeling poroelastic waves.
