The Bessel panel is a way to arrange a number of loudspeakers so that the angular sound distribution resembles that of a single speaker.
This model combines five Bessel panels in the same pattern to approximate a purely radial sound field. The speakers are driven with different signals, some of them in counter-phase. This results in an approximately homogeneous polar far-field distribution.
In this 3D model, the GMRES solver with the Geometric Multigrid preconditioner is used to ensure low memory consumption at a high mesh resolution.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
