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 how to build and solve a conductive heat transfer problem using the Heat Transfer interface. The model, taken from a NAFEMS benchmark collection, shows an axisymmetric steady-state thermal analysis. As opposed to the NAFEMS benchmark model, we use the temperature unit kelvin ... Read More
In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example ...

One method for removing cancerous tumors from healthy tissue is to heat the malignant tissue to a critical temperature that kills the cancer cells. This example accomplishes the localized heating by inserting a four-armed electric probe through which an electric current runs. Equations ... Read More
This problem follows a typical preliminary board-level thermal analysis. First perform a simulation of the board with some Integrated Circuits (ICs). Then, add a disk-stack heat sink to observe cooling effects. Finally, explore adding a copper layer to the bottom of the board in order to ... Read More
This example studies the stationary state of free convection in a cavity filled with air and bounded by two vertical plates. To generate the buoyancy flow, the plates are heated at different temperatures, set in a range to keep the flow laminar. Read More
This example describes the cooling and solidification, from melt to solid metal, in a continuous casting process. The model includes nonisothermal properties, temperature distribution, flow field, and phase change. This example uses the arbritrary Lagrangian-Eulerian method for modeling ... Read More
This model demonstrates how to compute satellite temperature over multiple orbit periods by coupling Orbital Thermal Loads to Heat Transfer in Solids. The direct solar, albedo, and Earth infrared thermal loads are computed over a single orbit, and are periodically repeated over multiple ... Read More
This tutorial shows how to use the Surface-to-Surface Radiation interface to simulate radiative heat transfer with radiation between diffuse emitters and diffuse-and-specular reflectors. This model is separated in two parts. The first part focuses on a validation test for the radiative ... Read More
When cooking food, such as a patty, in convection ovens there is a trade off in the heating method. If the patty is heated at a low oven temperature the cooking is slow and the patty dries out, resulting in a poor taste. If the patty is heated rapidly at a high temperature, it is ... Read More
In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon ... Read More
