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.
In a lithium metal battery, lithium metal is deposited during charging on the negative electrode. Mass transport and ohmic effects in the electrolyte cause small protrusions on the metal surface to be subjected to accelerated growth during charging. In worst case scenarios, this leads to ...

A battery’s possible energy and power outputs are crucial to consider when deciding in which type of device it can be used. A cell with high rate capability is able to generate a considerable amount of power, that is, it suffers from little polarization (voltage loss) even at high ... Read More
Impressed current cathodic protection is a commonly employed strategy to mitigate the ship hull corrosion where an external current is applied to the hull surface, polarizing it to a lower potential. In this model, the effect of propeller coating on the current demand is demonstrated. Read More
A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... Read More
Ion implantation is used extensively in the semiconductor industry to implant dopants into wafers. Within an ion implanter, ions generated within an ion source are accelerated by an electric field to achieve the desired implant energy. Ions of the correct charge state are selected by ... Read More
Anti-reflective coatings are frequently used in optical systems to reduce the amount of stray light produced when a beam of light crosses from one medium into another medium with a different refractive index. The simplest example of an anti-reflective coating is a quarter-wavelength ... Read More
In this tutorial model, you will see how to set up an eigenfrequency analysis of a rotor with multiple disks and bearings. The example illustrates how to use Campbell and stability diagrams to identify the critical speeds and the stability threshold. The rotor is modeled using the Beam ... Read More
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
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 ...

In this example, a torque is applied to the inner edge of a circular annulus-shaped membrane while the outer edge is fixed, resulting in membrane wrinkling. The wrinkling membrane model avoids the equilibrium instability that would be produced by the compressive stresses. The effect of ... Read More
