Topology Optimization of a Sound Partition Considering Acoustic-Structure Interaction
Application ID: 107441
This model demonstrates topology optimization for a problem involving acoustic-structure interaction for a sound partition problem. The objective being to reduce sound transmission for a fixed solid material fraction.
The design domain is modeled with a mixed formulation using the Solid Mechanics interface. The Density Model feature is used to setup a regularized topology optimization problem. The optimization problem is solved using GCMMA and continuation in the topology optimization parameters. The result is verified with a body-fitted mesh and compared to a simple design.

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.
