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.
Find the optimal cross section areas of trusses in a structure given a prescribed set of limitations and a clear objective. The structure is made up of trusses which are elements that can only sustain axial forces. Read More
This example shows how to model the behavior of a thermostat where a delay in its reaction has been implemented. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "How to Implement a Delay in Your Thermostat Simulation". Read More
This parametrized model can be used to simulate the hopping hoop problem. A rolling ring with a point mass on the perimeter can, under certain conditions, jump up from the surface on which it is rolling. A more detailed description of this model can be found in the blog post "The ... Read More
This is a demo model to show how to model connections in a mechanical system using Multibody Dynamics interface. In this model, pantograph mechanism is modeled. The purpose of this mechanism is to produce an identical, either enlarged or miniaturized, copy of an existing drawing. Read More
When estimating the parameters of a multiphysics model, both experimental noise and modeling uncertainties will contribute to corresponding uncertainties in the final parameters estimated. In this verification example, we demonstrate the new Variance functionality in the Parameter ... Read More
This model demonstrates one way of using equation-based modeling for generative design by using the powerful mathematical expression capabilities of COMSOL Multiphysics®. Read More
This example demonstrates an app that utilizes the LiveLink™ interface for Solid Edge® to run simulations on CAD designs. Read More
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Pro/ENGINEER via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
Thermally induced transformations in solids may be modeled by using an Arrhenius law to express the dependence on temperature of the transformation rate. This tutorial model shows how to use the Irreversible Transformation subfeature, available under the Solid feature of the Heat ... Read More
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
