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.
This tutorial models the thermal management of a polymer electrolyte membrane (PEM) fuel cell stack. Operating the stack with a similar temperature profile for all cells is important since an uneven temperature distribution may otherwise result in nonuniform water vapor condensation and ...

This series of models demonstrates how to do advanced electric machine modeling with COMSOL Multiphysics® — in 2D, 2.5D, and full 3D with end effects included. It investigates the performance of a Permanent Magnet Synchronous Motor, as is often used in modern electric vehicles. ... Read More
This tutorial shows how to model the propagation of acoustic waves in large pipe systems by coupling the Pipe Acoustics interface to the Pressure Acoustics interface. The tutorial is set up in both the time domain and the frequency domain. 1D pipe acoustics is used to model the ... Read More
Designing structures and open spaces with respect to sound quality is important for concert halls, outdoor environments, and even the rooms of a house. Simulating acoustics in the high-frequency limit, where the wavelength is smaller than the geometrical features, can be done with ray ... Read More
In this model, a full transient analysis of a loudspeaker driver is performed, which allow the modeling of nonlinear effects. It extends the linear frequency domain analysis done in the Loudspeaker Driver tutorial model. The analysis accounts for nonlinear behavior of the soft iron in ... Read More
Two embedded optical waveguides in close proximity form a directional coupler. The cladding material is GaAs and the core material is ion-implanted GaAs. The waveguide is excited by the two first supermodes of the waveguide structure - the symmetric and antisymmetric modes. Two numeric ... Read More
Metal hydride tanks offer safe hydrogen storage, thanks to their low reactivity, and a relatively high hydrogen density. When developing metal hydride hydrogen tank designs, modeling and simulation is useful for optimizing operating conditions, such as gas composition, pressure, and ... Read More
This tutorial model solves for an inductively coupled plasma reactor with RF bias (also known as ICP/CCP reactors) in a mixture of argon/chlorine. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Read More
This study simulates the thermal behavior of a computer Power Supply Unit (PSU). Most of such electronic enclosures include cooling devices to avoid electronic components to be damaged by excessively high temperatures. In this model, an extracting fan and a perforated grille cause an air ... Read More
