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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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.

Thermal Bridges in Building Construction — 3D Structure Between Two Floors

This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The ... Read More

Simulation of RF Tissue Ablation

This example exemplifies 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](/blogs/study-radiofrequency-tissue-ablation ...

Silica Glass Block Coated with a Copper Layer

In this time-dependent model, a silica block of glass, coated with a thin copper layer is subjected to a heat flux. Copper is a highly conductive material, while the silica glass is of poor thermal conductivity, which sets up an highly-varied temperature differential. The model must ... Read More


When a temperature gradient in a gas exists, suspended particles will tend to move from regions of high temperature to low. The force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the ... Read More

Natural convection in a closed cavity with mass conservation

Only fully compressible flow can guarantee the mass conservation in time in a closed cavity where the temperature increases. This is a simple proof of concept using the "gravity" option available in V5.2A. Read More

Shell Conduction

This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution. Read More

Temperature Field in a Cooling Flange

A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer ... Read More

Thermal Performances of Windows

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The ... Read More

Interpolating Material Data on a Regular Shape as an Alternative to Building an Irregular Geometry

Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ... Read More

Surface-to-Surface Radiation with Specular Reflection

The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using Ray Shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the Ray Shooting algorithm. The model is a standard benchmark ... Read More
