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 COMSOL Multiphysics, you can import mesh and interpolation data created by other software for use in your simulations. You can also export data created in COMSOL Multiphysics to use in other COMSOL models and applications as well as other software. This document and accompanying ... Read More
These examples demonstrate how to generate randomized geometric surfaces. Note that there is now also an add-in covering random surface functionality for planar surfaces. The COMSOL Multiphysics® software provides a powerful set of built-in functions and operators, such as ... 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 transformer model demonstrates how to extract the magnetizing and leakage inductances, along with parasitic capacitances. In this case, due to very high turns ratio, the secondary parasitic capacitance has a dominant effect when referred to primary. In experimental measurements, the ... Read More
Electromagnetic analysis of a 400kVA, 15kV/400V three-phase power transformer with Y-d connection and multiple primary and secondary coils with hundreds of turns. The model features the standard open- and short-circuit test in 2Daxi and 3D simulations to estimate electrical quantities ... Read More
This tutorial series demonstrates three different approaches to remove small geometric entities from an imported 3D CAD geometry of a wheel rim: the Repair operation, the Defeaturing tools, and the Remove Details operation. Use Repair to automatically find and remove small entities ... Read More
A Chladni plate is a metal plate that is covered in sand and subjected to vibrations. At certain frequencies, the vibrations produce standing waves, resulting in sand patterns formed on the plate. The vibrations are either formed from a violin bow at the side of the plate or a wave ... Read More
A 3D model of an acoustic trap in a glass capillary actuated by a piezoelectric transducer. The system is actuated by an oscillating electric potential across the piezoelectric transducer inducing mechanical vibrations in the solid and an acoustic pressure field in the fluid. The heat ... Read More
The majority of 3D CAD files include only the geometry of the product to be manufactured. For finite element analysis, however, you find yourself often in a situation where additional geometry is needed, for example, to analyze the flow inside or outside a device. This tutorial, ... Read More
Thermoelectric elements are often used to cool or heat electronic components to a desired temperature. In such simulations, you are typically not interested in the behavior of the thermoelectric element itself but want to use its performance characteristics to model the overall response ... Read More
