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.
Chemical vapor deposition (CVD) is a process often used in the semiconductor industry to grow layers of high-purity solid material on top of a wafer substrate. CVD is achieved using many different techniques and across a range of pressures from atmospheric to ultrahigh vacuum (UHV/CVD). ... Read More
High-power battery energy storage systems (BESS) are often equipped with liquid-cooling systems to remove the heat generated by the batteries during operation. This tutorial demonstrates how to define and solve a high-fidelity model of a liquid-cooled BESS pack which consists of 8 ... Read More
The backward facing step is an interesting case for studying the performance and solution strategy of a turbulence model. In this case, the flow is subjected to a sudden increase of cross-sectional area, resulting in a separation of flow starting at the point of expansion. Spatial ... Read More
The first model describes the simultaneous flow of two immiscible fluids in porous media - here air displaces water in a multi-step inlet pressure experiment. We solve for the pressure and the degree saturation for the air and water within a representative volume and so track saturation ... Read More
Cyclones are used in a variety of applications ranging from the mining industry to vacuum cleaners. The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate. In this tutorial example, the v2-f turbulence model is used to simulate the flow in a ...

Continuous mixing is used in process equipment to mix components in a single pass. Compared to batch mixing, this operation has the advantage that the tank filling and emptying steps are eliminated, implying that the process can be run without interruptions. A disadvantage of continuous ... Read More
This is a conceptual model illustrating how to couple fluid-structure interaction, heat transfer, and thermal expansion. A bimetallic strip in an air channel is heated so that it bends. After some time, an airflow with an inlet temperature which varies in time is introduced. As a ... Read More
This tutorial model solves the incompressible Navier-Stokes equations in a backstep geometry using the Laminar Flow interface. A characteristic feature of fluid flow in geometries of this kind is the recirculation region that forms where the flow exits the narrow inlet region. The model ... Read More
Many complex fluids of interest exhibit a combination of viscous and elastic behavior under strain. Examples of such fluids are polymer solutions and melts, oil, toothpaste, and clay, among many others. The Oldroyd-B fluid presents one of the simplest constitutive models capable of ... Read More
Aldicarb is a commercial pesticide, used on a variety of crops, including cotton, fruits, potatoes, and beans. This arises in the possibility that the general population may be exposed to aldicarb through the ingestion of contaminated water and foods. This example looks at the ... Read More
