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 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
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
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
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
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
Job Sequences to Save Data After Solving a Model
These examples demonstrate how to use a job sequence to perform a programmatic sequence of operations, including solving; saving the model to file; and generating and exporting plot groups, results, and images. In the blog post associated with these files, "How to Use Job Sequences to ... Read More
Geometric Parameter Optimization of a Bracket
This tutorial minimizes the mass of a bracket that is synchronized from Solid Edge® 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 ... Read More
User-Defined License Agreement in an Application
This example of a simulation application shows how to add a user-defined license agreement, which you can use to protect applications that you publish and distribute. Read More
How to Export Images Automatically After Solving
This example demonstrates how to use a parameterized slice plot and animation functionality to export a sequence of images. In addition, the example shows how to use a job sequence to perform a programmatic sequence of operations where the model is first solved and then the image ... Read More
