Which Problems Can You Solve?
The Acoustics Module interfaces handle acoustics in fluids (both quiescent and moving background flows) and solids. The physics interfaces for acoustics in fluids (pressure acoustics, thermoviscous acoustics, and linearized potential flow) support transient, eigenfrequency, frequency domain, mode analysis, and boundary mode analysis. The study of elastic and poroelastic waves in solids also has support for eigenfrequency and frequency domain analysis. The physics interfaces for solids support static, transient, eigenfrequency, and frequency response analysis. Further, by using the predefined couplings between fluid and solid interfaces, you can solve problems involving acoustic-structure interaction including the coupling to piezoelectric materials.
All categories are available as 2D, 2D axisymmetric, and 3D models, with the following differences.
•
The Acoustic–Shell Interaction interfaces are supported in 2D axisymmetric and 3D, and also require the addition of the Structural Mechanics Module.
•
The Pipe Acoustics interfaces exist on edges in 2D and 3D.
•
In 2D, the module has in-plane physics interfaces for problems with a planar symmetry as well as axisymmetric physics interfaces for problems with a cylindrical symmetry.
•
Some fluid acoustics interfaces are available in 1D and 1D axisymmetric geometries.
When using the axisymmetric models, the horizontal axis represents the r direction and the vertical axis the z direction. The geometry is in the right half plane.
