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 example extends a model of vibration and noise in a five-speed synchromesh gearbox for a manual transmission vehicle. A detailed roller bearing model is used to represent the bearing dynamics. The gearbox vibration is computed using a time-dependent analysis for a specified engine ... Read More
Gearboxes transmit power between shafts and can generate vibration and radiated noise during operation. Gear contact can transmit unwanted lateral and axial forces to the bearings and housing, while the flexibility of components such as the gear meshes, bearings, and housing contributes ... Read More
In applications where pressure waves and elastic waves propagate in porous materials filled with air, both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous ... Read More
Micromirrors are used in certain MEMS devices to control optical elements. This example of a vibrating micromirror surrounded by air uses the Thermoacoustic-Shell Interaction user interface to model the fluid-solid interaction, and it thus includes the correct viscous and thermal damping ...

An iron sphere in a magnetic field is an excellent textbook example to demonstrate the effects of a magnetic field interacting with a permeable material. This tutorial series is designed as an introduction to numerically modeling electromagnetic effects with COMSOL. This series ... Read More
In this classical benchmark model, a spherical scatterer is placed in a plane wave background field. When the sphere is modeled as sound hard, the problem has an analytical solution. The model compares the results using the Pressure Acoustics, Boundary Elements interface with the ... Read More
This is a tutorial model that illustrates the use of the scattered field formulation in acoustics. A solid object (here an ellipsoid) is hit by an incident plane wave field (background pressure field). The model solves for the scattered field. The model uses a PML and a far-field ... Read More
This example illustrates how to combine different Creep material models. Here a Norton–Bailey model (primary creep) is combined with a Norton model (secondary creep). This example is a continuation of the model thermally induced creep. Read More
