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.
Many engineering structures consist of thin and slender components, where a full solid model will result in many extremely small elements. For such structures, it is much more efficient to use shell or beam elements. In this tutorial and verification model, it is shown how to connect ... Read More
This model illustrates the effect of oxygen and hydrogen formation and recombination on the performance and self-discharge of an electrochemical capacitor with a water-based electrolyte. A load cycle consisting of mixed constant current pulses and rest periods at an open circuit is ... 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
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, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... Read More
This model represents a test case of a flow in an elastic tube which is present in several applications. This specific case models viscoelastic flow and represents steady flow in a channel in which part of the upper wall is replaced by an elastic plate subjected to an external pressure. ... Read More
This model shows how to compute the thickness of a thermally evaporated gold film. The thickness of the deposited film is computed both on the walls of the chamber and on the sample. Read More
This example demonstrates simulation of a turbulent flow in a geometry with an air filter. Porous material of the filter induces an abrupt pressure drop and drastic increase of turbulence level inside the filter. Read More
Interference fit is a technique used to join two parts by fitting one over or around the other. The inner part is cooled so that it shrinks and can be fitted on the outer part. Once the part returns to its original temperature and expands, a contact pressure builds up at the interface ... Read More
