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.
Notch Approximation in Low-Cycle Fatigue Analysis of Cylinder with a Hole
A load carrying component of a structure is subjected to multi-axial cyclic loading during which localized yielding of the material occurs. In this model you perform a low cycle fatigue analysis of the part based on the Smith-Watson-Topper (SWT) model. Due to localized yielding, you ... Read More
Rolling Contact Fatigue in a Linear Guide
When a linear guide is loaded above the manufacturer's specification limit, one concern is whether the contact loads will introduce fatigue spalling. In this system analysis, the entire guide has been analyzed and the mostly damaging contact load has been identified to occur on a rail ... Read More
Acoustics of a Living Room
Prevent shaking windows and enhance the sound experience by careful positioning of the loudspeakers in your room. This tutorial analyzes the low frequency response of a living room to the woofer units of two loudspeakers, and solves for the eigenfrequencies of the room. The room geometry ... Read More
White Pupil Échelle Spectrograph
Échelle spectrographs are commonly used in astronomy for high-resolution analyses of stellar atmospheres and for precision Doppler velocimetry. This tutorial simulates a "white pupil" form of this instrument. It makes use of several parts from the COMSOL Part Library and demonstrates the ... Read More
Vortex Lattice Formation in a Rotating Bose–Einstein Condensate
This tutorial model solves the Gross–Pitaevskii Equation for the vortex lattice formation in a rotating Bose–Einstein condensate bound by a harmonic trap. The equation is essentially a nonlinear single-particle Schrödinger Equation, with the inter-particle interaction represented by a ... Read More

1D Isothermal Nickel–Cadmium Battery
This model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. Read More
Acoustics of Coupled Rooms Using the Acoustic Diffusion Equation
This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. Read More
