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. 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.
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 ...

In this example, a spring-loaded valve-opening mechanism consisting of a rocker arm and a radial cam is studied. All of the system components are modeled as rigid and are connected through prismatic, hinge, and slot joints. The cam-follower connection as well as other joint connections ... Read More
Piezoelectric microblowers are compact, lightweight air pumps with varying applications including electronics cooling and airflow related medical devices. The device consists of a PZT-brass diaphragm and a specially designed housing including a pumping chamber, air inlet and outlet ... Read More
This conceptual model analyzes the influence of leaks on the acoustic response of an earbud speaker placed in an ear-canal-like geometry. Built-in impedance models are used to capture the effects of a perforated plate in front of the speaker, skin impedance, and ear drum impedance. The ... Read More
Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. ... Read More
This model demonstrates how to set up a phase field damage multiphysics model to predict crack propagation in thermoelastic solids under large deformations. The crack-driving force depends on the principal stresses, which in turn depend on the temperature distribution in the solid ... Read More
This model utilizes the thermoviscous acoustic interface in a sub-model to obtain detailed results for the transfer impedance of a perforated plate (including the thermal and viscous losses). The impedance is in turn used as an internal impedance in a pressure acoustic model of a ... Read More
The Whirling of a Uniform Shaft tutorial model shows you how to perform a transient analysis of a uniform shaft under gravity. The shaft is supported by two hydrodynamic bearings at its ends. The gyroscopic effect causes the rotor to whirl about its initial axis and the rotor eventually ... Read More
This model demonstrates how to set up a dynamic simulation that includes several contact interactions, including friction, using a single general contact pair. The dynamics is solved using explicit time stepping. Read More
This app demonstrates the following: Reading and importing data from an Excel®-file Exporting data to an Excel®-file Light theme The app computes the beam section properties and true stress distribution in a designated steel beam section. A broad range of American and European beam ... Read More
