Introduction to Modeling Acoustic-Structure Interactions in COMSOL®
To model an ASI problem, you need to account for the behavior of elastic waves in solids, pressure waves in fluids, and their interaction. The COMSOL® software includes interfaces for doing so.

Performing Topology Optimization with the Density Method
The density method simplifies the process of topology optimization. Get an overview of how to use a special density feature for topology optimization in the COMSOL® software.

Course: Defining Multiphysics Models
There are 3 approaches to setting up a multiphysics model in the COMSOL® software: Fully automatic, manual with predefined couplings, and manual with user-defined couplings. Here, we discuss #1.
