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 example shows how to set up multiple sandwiched thin layers with different thermal conductivities in two different ways. First, the composite is modeled as a 3D object. In the second approach the Thin Layer boundary condition with the thermally thick option is used to avoid ... Read More
Compact camera modules are widely used in electronic devices such as mobile phones and tablet computers. In order to reduce both the size and number of elements required the optical design will typically incorporate several highly aspheric surfaces. This model demonstrates a five element ... Read More
The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using parameter, shape and topology optimization. Read More
The Black-Scholes equation, computes the value u of a European stock option. Black-Scholes derived an analytical expression for the solution to this problem. However, the formula works only for certain cases; for instance, you cannot employ it when sigma and r are functions of x and t. ... Read More
The pyrolysis of a centimeter-sized wood particle presents a fully coupled multiphysics problem with mass transfer, fluid flow, and heat transfer. This example model consists of two parts. The first part demonstrates how to set up a model describing the pyrolysis of a porous, ... Read More
In this tutorial, the propagation of elastic waves in the ground after a seismic event is simulated using a 2D model. The effect of the ground surface topology on the wave propagation is illustrated when an ideal half space is modified with the presence of a small mountain. The model is ... Read More
A thermoelectric leg is a fundamental component of a thermoelectric cooler (or heater). For example, a thermocouple is a thermoelectric module typically made of two thermoelectric legs: one made of p-type and of one n-type semiconductor material which are connected in series electrically ...

This model is a benchmark problem from TEAM workshop (problem 15 part I, see https://www.compumag.org/wp/team/). The model simulates the behavior of a coil as it scans a conductive plate containing a defect (a crack). The computed coil parameters, which include change in resistance and ... Read More
This example investigates the electrical performance of a cascaded cavity filter operating in the millimeter-wave 5G band with temperature changes. The thermal variations result in structural deformations of the structure. Thus, the resonant frequencies of the filter elements (cavities) ... Read More
This model shows how to add several linked mobility models to the simple MOSFET example. Read More
