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.
In nuclear fusion reactors, the conducting fluid, such as the fusion plasma and the liquid metal in the reactor blanket, will interact with the background magnetic field. This phenomenon is referred to as magnetohydrodynamics (MHD). The electromagnetic field and fluid flow are fully ... Read More
In this first half of a two-part example, a 2D model of a trench-gate IGBT is built, which will be extended to 3D in the second half. In general, it is the most efficient to start with a 2D model to make sure everything works as expected, before extending it to 3D. The Caughey&ndash ... Read More
This model demonstrates how to define Earth properties that are spatially varying on the planet. A satellite in orbit experiences solar, albedo, and planetary infrared (IR) loads, where albedo and planetary IR can vary with latitude and longitude. In this example, these inputs are read ...

This model simulates an H-shaped micro-cell designed for diffusion-controlled separation. The cell puts two different laminar streams in contact for a controlled period of time. The contact surface is well-defined and, by controlling the flow rate, it is possible to control the amount of ... Read More
Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... Read More
This application presents an example of pressure driven flow and electrophoresis in a 3D micro channel system. Researchers often use a device similar to the one in this model as an electrokinetic sample injector in biochips to obtain well-defined sample volumes of dissociated acids and ... Read More
In this example, the importance of including elastic deformations when analyzing heavily loaded fluid-film bearings is investigated. The structural parts are modeled using the Solid Mechanics interface, while the pressure in the lubricant is determined by the means of the Hydrodynamic ... Read More
In this shape optimization example, the mass of a bracket is minimized by changing the size and position of a number of geometrical objects. The requirements give limits both on the lowest natural frequency, and on the maximum stress in a static load case. This means that results from ... Read More
In this example, the brittle fracture of a holed plate with a notch is modeled using a phase-field damage model. The geometry of the plate is set up so that a mixed-mode fracture is induced, with dimensions and material properties taken from experimental data. The example shows how to ... Read More
Fluid dampers are used in military devices for shock isolation and in civil structures for suppressing earthquake-induced shaking and wind-induced vibrations, among many other applications. Fluid dampers work by dissipating the mechanical energy into heat. This model shows the phenomenon ... Read More
