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.

SmartUQ Engineering Analytics Light-Weighting Application with COMSOL FEA Bracket Example

For decades, light-weighting has been a major area of research and concern in the automotive and aerospace industries. Industry leaders are adopting new software tools and investing ever greater engineering resources in adapting and optimizing their designs to be as lightweight and ... Read More

Modifying Imported CAD Geometry with the Deformed Geometry Interface

When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ... Read More

Spinodal Decomposition Benchmark

Many important processes in the mesoscale can be described by phase-field models. One of the oldest phase-field problems is the spinodal decomposition. Several standardized benchmark problems have been developed by the phase-field community. In this entry, these problems are solved using ... Read More

Modeling the Forces in a Bicycle Rim

Bicycle wheels are laced tangentially if they are intended to be used with disc brakes, because a radial pattern gives rise to larger forces in the rim. Otherwise, these rim forces are largely independent of the braking force. Read More

Stress Analysis of a Pipe Fitting from a CAD File

This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D CAD geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL. A cutting plane is defined ... Read More

Mechanical Precession for the Axle of a Bicycle Pedal

Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. Read More

Golf Ball Trajectory

This model is used in the blog post "Why Do Golf Balls Have Dimples?". The trajectory of a golf ball is compared to the trajectory of a smooth ball using the Events interface and a system of ODEs in a 0D component. Read More

Geometric Parameter Optimization of a Bracket

This tutorial minimizes the mass of a bracket that is synchronized from PTC® Creo® Parametric™ via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical ... Read More

Micromechanical Model of a Composite with Temperature-Dependent Material Properties

The homogenized material properties of a composite are computed based on the temperature-dependent properties of matrix and fiber. The homogenized parameters are compared to the analytical values derived from the rule of mixtures. This is an extension of model https://www.comsol.com ... Read More

Geometric Parameter Optimization of a Bracket

This example minimizes the mass of a bracket that is synchronized from Inventor® via the LiveLink™ interface. There are limits both for the lowest natural frequency, and for the maximum stress in a static load case. The size and position for a number of geometrical features is changed ... Read More
