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 illustrates the dynamics of helical gears. It is built using the gears functionality in the Multibody Dynamics interface in COMSOL Multiphysics. A transient study is performed to analyze the effect of constant gear mesh stiffness, varying gear mesh stiffness, and the ... Read More
Silicon micromechanical resonators have long been used for designing sensors and are now becoming increasingly important as oscillators in the consumer electronics market. In this series of models, a surface micromachined MEMS resonator, designed as part of a micromechanical filter, is ... Read More
As integrated circuit (IC) technology advances, with circuits becoming more powerful and compact, it is increasingly important to identify and prevent any cause of circuit failure. One particularly critical factor contributing to circuit failure is electromigration within the ... Read More
Composite materials are often used in structural applications because their properties, such as stiffness and strength, can be tailored to meet specific requirements. This makes them attractive alternatives to traditional engineering materials. Composites are also used in applications ... Read More
Delamination or the separation of layers is a common failure mode in laminated composite materials. Various factors, including loading, defects in the material, and environmental conditions, can trigger the initiation and propagation of layer separation. This leads to degraded structural ...

In this example, the structural integrity of a cylinder made of a fiber-reinforced composite is assessed at both the macroscale and the microscale. In addition to macroscale analyses, structural composites require microscale stress and failure analyses to identify the critical ... Read More
Buckling is a structural instability that can cause a component to fail even when the material remains within the elastic regime. Therefore, determining the critical buckling loads and corresponding mode shapes can be important from a design perspective, even when the applied loads ... Read More
This example studies the deflection of a cantilever beam undergoing very large deflections. The beam is modeled using the Solid Mechanics, Shell, and Beam interfaces. The results are compared with each other and with a benchmark solution from NAFEMS. In addition, a linear buckling ... Read More
Electrochemical impedance spectroscopy (EIS) is a common technique in which a small oscillating perturbation is applied to an electrochemical system in order to investigate kinetic and transport properties. This example models EIS for a range of electrode reaction rates. Nyquist and Bode ... Read More
Nowadays, there is a trend toward manufacturing wheel rims from composite materials instead of aluminum. The main motivation is to reduce unsprung mass, which improves dynamic response and can enhance acceleration, braking, and cornering performance. Carbon-fiber-reinforced polymer ... Read More
