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.
Chemical engineering students can model a nonideal tubular reactor, including radial and axial variations in temperature and composition, and investigate the impact of different operating conditions with this easy-to-use app. The process described by the Tubular Reactor with ... Read More
This tutorial studies the propagation of high intensity focused ultrasound (HIFU) though a tissue phantom. HIFU is used in many different biomedical applications such as thermal ablation of tumors, transcranial HIFU surgery, shock wave lithotripsy, etc. A HIFU transducer typically ... Read More
In this tutorial, the heat and mass transport equations are coupled to laminar flow in order to model exothermic reactions in a parallel plate reactor. It exemplifies how you can use COMSOL Multiphysics to systematically set up and solve increasingly sophisticated models using predefined ... Read More
This model shows how to compute the anchor loss limited quality factor of a diamond disc resonator. The resonator is anchored to the substrate by a polysilicon post and power is transmitted to the substrate through the post. A perfectly matched layer is used to represent the essentially ...

Lithium-sulfur (Li-S) batteries are used in niche applications with high demands for specific energy densities, which may be as high as 500-600 Wh/kg. The chemistry is fairly complex, since multiple polysulfide species participate in the various charge transfer reactions. The chemistry ... Read More
Tubular reactors are often used in continuous large-scale production, for example in the petroleum industry. One key design parameter is the conversion, or the amount of reactant that reacts to form the desired product. In order to achieve high conversion, process engineers optimize the ... Read More
This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Read More
This model demonstrates how to perform a hearing aid acoustic feedback response analysis, including both the in-ear hearing aid and the hearing aid cassette. The hearing aid modeled is a ReSound OMNIA™ device from GN Hearing A/S. The hearing aid is tested on a combined pinna and ear ... Read More
The mass of an aluminum beam is minimized subject to a displacement constraint and a distributed load. The problem is solved using parameter, shape and topology optimization. Read More
An iron sphere in a magnetic field is an excellent textbook example to demonstrate the effects of a magnetic field interacting with a permeable material. This tutorial series is designed as an introduction to numerically modeling electromagnetic effects with COMSOL. This series ... Read More
