Spherical Scatterer: BEM Benchmark
Application ID: 56141
In this classical benchmark model, a spherical scatterer is placed in a plane wave background field. When the sphere is modeled as sound hard, the problem has an analytical solution.
The model compares the results using the Pressure Acoustics, Boundary Elements interface with the analytical solution for several frequencies. The results show very good agreement. The model results do not show any irregular modes.
This model example illustrates applications of this type that would nominally be built using the following products:Acoustics Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
