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 exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products. The model also includes secondary current distribution electrode kinetics on the protected steel ... Read More
Although initially invented to be used in printers, inkjets have been adopted for other application areas, such as within the life sciences and microelectronics. Simulations can be useful to improve the understanding of the fluid flow and to predict the optimal design of an inkjet for a ... Read More
In this example, a lumped model of a vehicle suspension system having 11 degrees of freedom is analyzed. The Mass, Spring, and Damper nodes of the Lumped Mechanical System interface are used to model the wheels, including suspension system as well as the seats with a passenger. The ... Read More
A radome minimizes losses and improves radiation characteristics of an antenna through its design. The structure can be optimized to minimize the transmission loss and also designed to improve radiation characteristics including antenna directivity and side lobes. Shown in the model is ...

This example demonstrates the modeling of a sandwiched composite blade made up of carbon–epoxy, glass–vinylester, and PVC foam materials. Three different methods are used to model the sandwich composite structure: Layerwise theory, Equivalent Single Layer (ESL) theory, and a multiple ... Read More
This example simulates 3D unsteady laminar flow past a cylinder in a channel. The inflow velocity profile is time-varying. The lift and drag coefficients are computed, and results show good agreement with those published in the literature. Read More
This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The ... Read More
Deposition of metallic lithium on the negative electrode in preference to lithium intercalation is known to be a capacity loss and safety concern for lithium-ion batteries. Harsh charge conditions such as high currents (fast charging) and/or low temperatures can lead to lithium plating. ... Read More
Electrochemical codeposition is a common low-cost method for producing metal alloys. This tutorial model demonstrates electrodeposition of a nickel (Ni)–phosphorous (P) alloy. The model accounts for charge and mass transport of a multitude of species along with multiple electrode ... Read More
The thermal stress in a layered plate is studied in this example. A plate consisting of two layers, a coating and a substrate layer, is stress and strain free at 800 degrees C. The temperature of the plate is reduced to 150 degrees C and thermal stresses are induced due to the difference ... Read More
