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.
Commercial heat exchangers often feature a complex design. It is significantly easier to build a design with new CAD parameters than to build designs with novel topologies. This model demonstrate how to optimize the size and position of the tubes in a tube and shell heat exchanger. It is ... Read More
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This example simulates splitting properties using a simplified 2D geometry. The geometry is optimized using shape optimization in order to get the ... Read More
This model illustrates how to improve the symmetry of a wet chemical etching process by varying the convection and chemical concentration as a function time. Read More
The installation verification application can be used to help verify that your COMSOL Multiphysics® or COMSOL Server™ installation works as expected on your hardware platforms and operating systems. The app automatically loads and runs a suite of test models and compares the results with ... Read More
The purpose of this application is to generate response spectra from a time history which can consist of either measured data on a file, or an analytical function. Primarily, the target is to provide input to a response spectrum analysis. The graphs can, however, also be used to ... Read More
This model demonstrates how to use the built-in shape optimization functionality to improve the performance of a plate heat exchanger. The optimization reduces the path immediately in front of the inlets and outlets to increase the length of typical streamlines. This leads to a improved ... Read More
The Dzhanibekov effect, also called the intermediate axis theorem or tennis racket theorem, describes the behavior of a rigid body with three distinct principal moments of inertia. This simulation app can be used to test the Dzhanibekov effect in three different geometries, including a ... Read More
Indentation tests are commonly used to evaluate the safety of battery cells by assessing the risk of internal short circuits under external mechanical loads. This example demonstrates how to set up such a test, in which an indenter is pressed onto a battery cell, causing large ... Read More
This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radiofrequency Tissue Ablation Using Simulation". Read More
Electrical cables, also called transmission lines, are used everywhere in the modern world to transmit both power and data. These cables carry electromagnetic energy, but instead of dealing with the full complexity of the electromagnetic fields, they are more commonly classified ... Read More
