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 tutorial demonstrates how a lumped model of a MEMS transducer can be derived from its FEM model. It includes an FEM model of a capacitive micromachined ultrasonic transducer (CMUT) and the corresponding lumped model created using the Lumped Mechanical System (LMS) interface. The ... Read More
Prismatic lithium cells are widely used in electric vehicles and battery energy storage systems. This example demonstrates the use of the Lithium-Ion Battery interface for a full 3D prismatic battery equipped with two jelly rolls. The model defines a full so-called Newman model but ... Read More
This tutorial is a benchmark model that reproduces the Testing Electromagnetic Analysis Method (TEAM) Problem 32, which evaluates numerical methods for the simulation of anisotropic magnetic hysteresis. A hysteretic three-limbed laminated iron core is subject to a time-varying magnetic ... 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 presents a study of positive and negative corona discharges in dry air at atmospheric pressure. The discharges are sustained within two electrodes in a coaxial configuration by a high voltage DC source applied to the inner electrode. Two different types of models are used: ... Read More
A tapered optical waveguide structure is used for matching two waveguides having different geometric cross sections and/or different material parameters. The tapered waveguide has one geometric cross section at the input plane and another cross section at the output plane. In between ... Read More
A radio frequency quadrupole ion trap utilizes a radio frequency quadrupole (RFQ) in order to trap an ion beam. A continuous high energy ion beam is first cooled and converted into a spatially confined bunch, which can then be released with minimal heating of the beam. The device is also ... Read More
This model demonstrates the polarization properties for a Gaussian beam incident at an interface between two media at the Brewster angle. The model shows how to use the Electromagnetic Waves, Beam Envelopes physics interface with a User defined phase specification. Matched Boundary ... Read More
This example treats a pulmonary artery stenosis as a porous medium and demonstrates how to set up a model that combines free and porous media flow of a non-Newtonian fluid. The non-Newtonian behavior of blood is modeled using the Carreau model. Read More
Thermal energy storage units are used to accumulate thermal energy from solar, geothermal, or waste heat sources. The simplest units are built from water tanks, often found in households, where the solar energy is stored as sensible heat. The thermal capacity of these tanks can be ... Read More
