The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
Sound Transmission Loss Through a Window new
This model presents a practical and efficient method to compute the sound transmission loss (STL) through a building component, specifically this example treats the case of a double glazed window. The method used here is valid for structural components which have small influence on the ... Read More
Absorptive Muffler with Shells
This model describes the pressure wave propagation in a muffler for an internal combustion engine. The purpose of the model is to show how to analyze both inductive and resistive damping in pressure acoustics as well as coupling the fluid to the surrounding elastic shell structure of the ...

Acoustic Mean Free Path in a Room
This model uses the *Ray Acoustics* interface to extract statistical information about a room. Two examples of rooms are analyzed: 1. The staircase from the [One-Family House Acoustics tutorial model](/model/one-family-house-acoustics-20169) 2. A long corridor The models compute the ... Read More
Diesel Particulate Filter Analysis Using an Acoustic Transfer Matrix
Diesel particulate filters (DPFs) are designed to remove and filter soot (diesel particles) from the exhaust of diesel engine vehicles. The filters in such systems are typically structured with long, air-filled channels surrounded by a porous medium that retains the soot. Although the ... Read More
