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 example simulates an air-cooled cylindrical 18650 lithium-ion battery during a charge-discharge cycle, followed by a relaxing period. A lumped (0D) cell model is used to model the battery cell chemistry, and a two-dimensional axi-symmetrical model is used to model the ... Read More
It is often not possible to insert a normal microphone directly into the sound field being measured. The microphone may be too big to fit inside the measured system, such as for in-the-ear measurements for hearing aid fitting. The size of the microphone may also be too large compared to ...

This benchmark example builds two models of a cross-bridge Kelvin resistor used for extracting the specific contact resistivity. The first model simulates the system in 3D, using the contact resistance feature built in the Semiconductor interface. The other model is a 2D approximation of ... Read More
This tutorial model uses a heat sink geometry from the Part Library. The tutorial shows different approaches to heat transfer modeling when studying the cooling of an electronic chip. In the first part, only the solid parts are modeled, while the convective airflow is modeled using ... Read More
An Evans droplet experiment is a century-old corrosion experiment for demonstrating oxygen transport-limited corrosion. A droplet of water is placed on a metal surface, and over time the surface features differences in the radial direction of the surface in terms of amount of corroded ... Read More
This model simulates a simple three-dimensional axisymmetric Helmholtz resonator, a classic acoustics model of a resonating circuit with a known theoretical solution. The idealized version considered here consists of a tube and a closed volume in series which are exposed to a pulsatile ... Read More
This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between the Solid Edge® software and the COMSOL Multiphysics® software, how to modify the geometry from COMSOL Multiphysics®, and how to run a geometric ... Read More
This model demonstrates how to model phenomena defined in different dimensions in a fully coupled manner using COMSOL Multiphysics. Whereas in most cases the reaction rate expression is defined as a function of the concentrations of the reactants and products, in adsorption reactions ... Read More
A thin-walled metal frame with a central cutout, modeled using the Shell interface, is subjected to twisting and bending. Around the cutout the stresses are higher than the yield stress, thus the material undergoes plastic deformation over the loading history. Read More
This non-conventional model of porous media flow utilizes creeping (Stokes) flow in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya Sirivithayapakorn of the University of California, Santa Barbara. ... Read More
