In this article, we discuss how to perform this specific type of multiphysics coupling and direct you to resources that provide further details on how to accomplish this for different scenarios.

An empty Multiphysics node is added automatically when two (or more) physics interfaces are set up in a model and when there is the possibility to couple the physics interfaces.

In COMSOL Multiphysics ®, you can manually administer couplings between physics interfaces for which no coupling features are available. We refer to this as the manual approach with user-defined …

5 days ago · This blog post introduces the capabilities of COMSOL Multiphysics for coupling acoustics and ray tracing for 2 automotive applications: car cabin acoustics and an acoustic car parking sensor.

Supercharging Multiphysics Modeling: How Cosmon’s AI Agent Elevates Engineering Workflows in COMSOL Engineering is the art of managing complexity. At Carnegie Mellon, I learned that great …

Dec 5, 2025 · A demonstration at the conference showed how to use the software to model a capacitive touchscreen. Sjodin noted that Comsol Multiphysics electromagnetic simulations include modules …

To add a Multiphysics Coupling, right-click the Physics Interface or Multiphysics Interface nodes to add this from the context menu. This node contains settings for specifying which coupling type the …

The coupling features in this list are available to all Multiphysics Coupling nodes. If the multiphysics coupling is in the same builder file, use Local in the Link from list.

In order to distinguish between variables belonging to different coupling nodes or physics interfaces, the name string must be unique. Only letters, numbers, and underscores (_) are permitted in the Name …

In this section, a few tips and tricks for modeling acoustics and vibration problems using the multiphysics couplings are presented.
