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 this example, the Bergstrom–Bischoff material model is used to model the temperature and strain dependent behavior of High Density Polyethylene (HDPE) used, for example, to make liners for damaged pipes in oil and gas applications, or to make type IV hydrogen storage vessels for fuel ...

This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Read More
This model demonstrates how to couple the Radiative Beam in Absorbing Media interface to the Radiation in Absorbing-Scattering Media interface. To learn more about this model, see our accompanying blog post “Modeling Absorption and Scattering of Collimated Light”. Read More
A model comparing the magnetization material models in time-dependent and frequency domain studies. Effective B-H curves are used for frequency domain. A linear relative permeability is included as reference. 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. The main advantage of DBRs over ordinary metallic mirrors is that DBRs can be engineered to have custom ... Read More
This tutorial illustrates how to use built-in variables and operators, for the evaluation of the bulk temperature along a geometry like a channel, a pipe or a chimney, in a nonisothermal flow in 2D and 3D. The bulk temperature may be needed to compute the heat transfer coefficient for an ... Read More
This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radiofrequency Tissue Ablation Using Simulation". Read More
The liquid electrolyte in lithium-ion batteries (LIBs) typically consists of a lithium salt, such as LiPF6, dissolved in one or several solvents. Commercial LIBs commonly employ a mix of multiple hydrocarbon-based solvents along with additional additives. In an electrolyte consisting of ... Read More
For transient acoustic problems, there are different sound pressure level metrics that have been defined in the literature and in measurement standards. These metrics are important to know when comparing results from a transient acoustic simulation to measurements from a sound level ... Read More
The design of antireflective coating plays an important role to increase the transmission of the infrared light that propagates through optical structures such as lens and windows. In this model, we showcase how different bulk structures such as Si and CZT that has the bulk ... Read More
