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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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.


1D Isothermal Lithium-Air Battery

Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. The theoretical value is about 11400 Wh/kg which is around 10 times greater than the lithium-ion batteries. In this tutorial, discharge of a lithium-air battery is ... 詳細を見る

Flexible and Smooth Strip Footing on Stratum of Clay

A common verification model for geotechnical problems is of a shallow stratum layer of clay. In this model, a vertical load is applied to the clay strata top surface and the static response and collapse load are studied. The clay is modeled as an elastic-perfectly plastic material ... 詳細を見る

Dipole Antenna with a Quarter-Wave Coaxial Balun

An antenna balun blocks undesirable currents on the outside of a cable. A quarter-wave coaxial balun (1:1) is one of the easiest designs: it works as a transformer and makes the input impedance from the inner conductor to the outer conductor infinite. This model simulates an antenna ... 詳細を見る

Truck Mounted Crane

Many trucks are equipped with cranes for load handling. Such cranes have a number of hydraulic cylinders, controlling the motion, and several mechanisms. The cylinders and mechanisms that make up the crane are subjected to large forces when handling heavy loads. In order to determine ... 詳細を見る

Vibrations in a Compound Gear Train

This model simulates vibrations in a compound gear train. Spur gears, used to model the gear train, are mounted on rigid shafts. The shafts are supported by an elastic housing at both ends. The gear mesh is assumed to be elastic with varying stiffness, which is the source of vibration. A ... 詳細を見る

Shell Conduction

This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution. 詳細を見る

Postbuckling Analysis of a Hinged Cylindrical Shell

The model studied is a benchmark for a hinged cylindrical panel subjected to a point load at its center. A linear buckling analysis predicts the critical buckling load. Such an analysis will however not give any information about what happens at loads higher than the critical load. ... 詳細を見る

Computing Intercepted Flux

This example model demonstrates four different approaches for computing the integrals of fields over arbitrarily placed geometries that can be re-positioned without having to re-solve the model. This approach is also useful if you want to integrate the results of a model over different ... 詳細を見る

Terzaghi Compaction

Fluids that move through pore spaces in an aquifer or reservoir can shield the porous medium from stress because they bear part of the load from, for instance, overlying rocks, sediments, fluids, and buildings. Withdrawing fluids from the pore space increases the stress the solids bear, ... 詳細を見る

Chemical Reactions and Soot Build-Up in a Diesel Filter

In this tutorial, a filter system for a diesel engine is modeled, including where a soot layer builds up and is oxidized. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to carbon monoxide and carbon dioxide, which in ... 詳細を見る
