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.

Modeling Deforming Meshes

This presentation and series of models show how to use the Deformed Mesh interfaces to model small and large translations and rotations of objects. A more detailed description of these models can be seen in the blog post Model Translational Motion with the Deformed Mesh Interfaces and ... Read More

Thermal Actuator Surrogate Model Application

The Thermal Actuator Surrogate Model application demonstrates how to accelerate computation for multiphysics analysis using a surrogate model. A surrogate model is a simpler, usually computationally cheaper model, which is used to approximate the behavior of a more complex, and often ... Read More

Galvanic Corrosion of a Magnesium Alloy in Contact with Steel

Magnesium alloys are attractive alternatives as lightweight materials in various fields of engineering. Magnesium is however relatively non-noble and may suffer considerable galvanic corrosion when being used in conjunction with other metals, for instance when mounting an Mg alloy ... Read More

Polymerization in Multijet Tubular Reactor

In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are ... Read More

Buckling of a Composite Cylinder

Buckling is a structural instability that can lead to failure of a component even without initial material failure. Computation of the critical buckling loads and mode shapes can therefore be important from a design viewpoint, even though it has previously been determined that the ... Read More

Three-Phase Mixer

This model simulates the separation and mixing of a suspension with light and heavy particles. Initially the distribution of both particle populations is homogeneous throughout the fluid. Before the impeller starts rotating, the fluid and the two particle populations tend to separate ... Read More

Water and Carbon Dioxide Co-Electrolysis in a Solid Oxide Electrolyzer Cell

This example models co-electrolysis of H2O and CO2 using a solid oxide electrolyzer cell. The model includes the full coupling between the mass balances and gas flow in the H2 and O2 gas diffusion electrodes, the momentum balances in the H2 and O2 gas flow channels, the energy balance ...

Lumped Loudspeaker Driver Using a Lumped Mechanical System

Example of a moving-coil loudspeaker where lumped parameters represent the behavior of the electrical and mechanical components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented using the Electric Circuit interface. The ... Read More

Heat Generation in a Vibrating Structure

This example models heat generation in a beam-like structure subjected to small amplitude vibrations. The model computes the linear elastic response in the frequency domain. The transient heat-transfer analysis simulates the slow-rising temperature in the beam using the heat generated ... Read More

One-Family House Acoustics

This model shows an application of the Acoustic Diffusion Equation physics interface. The acoustics in a two-story one-family house consisting of 10 rooms is analyzed. The steady state sound pressure level and energy density distributions are analyzed for a monopole source located in ... Read More
