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 of a two-story house can be used to examine a contaminant leak and the subsequent contaminant dispersion that occurs due to convection and diffusion. Airflow and recirculation within the home are dependent on vent placement, and flow velocity may also vary at each vent. ... Read More
This model demonstrates how to vary the inlet temperature in a superheated steam drying process so as to minimize the time, while constraining both the energy consumption and the final moisture content. Read More
The example concerns a stainless-steel MEMS heat exchanger, which you can find in lab-on-a-chip devices in biotechnology and in microreactors such as for micro fuel cells. This model examines the heat exchanger in 3D, and it involves heat transfer through both convection and ... 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 ...

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
The model demonstrates the basics of the 3-omega method. The coupled electromagnetic heating problem is solved in a solid sample which is heated by a thin copper strip, deposited on the surface of a sample. Analyzing the frequency dependence of the voltage oscillation amplitude, we ... Read More
When simulating surface-to-surface radiation, we rely on the view factors between elements of diffuse surfaces that emit and receive radiation. To compute surface-to-surface radiation in a given geometry, operators are created by the heat interface and can be used to evaluate view ... Read More
Basin-type insulators are essential components in Gas-Insulated Metal-Enclosed Switchgear (GIS). During manufacturing, the epoxy resin curing process can generate residual stresses that may lead to crack formation. Over time, such cracks can trigger partial discharges, degrading the ... Read More
This model illustrates the greenhouse effect in a box covered by a plate and exposed to sun radiation over a day. The temperature variation is monitored in two cases: with a plate made of glass, transparent in the solar spectral band and opaque for the ambient solar band with a fully ... Read More
This simple example covers the heating of a finite slab and how the temperature varies with time. We will set up the problem in COMSOL Multiphysics after which we compare the solution to the analytical solution. Read More
