Topology Optimization and Verification of an Acoustic Mode in a 2D Room
Application ID: 44501
This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the sealing of a 2D room, that minimizes the average sound pressure level in an objective region. The optimization is carried out for a single frequency. The topology optimized design is further transformed into a geometry and the results of the optimization are verified using actual sound hard boundaries.
The model requires the Optimization Module and the Acoustics Module.
This model example illustrates applications of this type that would nominally be built using the following products:
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.
