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.
When two coherent light beams intersect, an interference pattern appears. If this occurs in a material that is sensitive to light, with intensities greater than a certain exposure threshold, the interference pattern is recorded in the material as a modulation of the refractive index and ...

This model simulates the discharge of a Nickel-Metal Hydride (NiMH) battery using the Battery with Binary Electrolyte interface. The geometry is in one dimension and the model is isothermal. The model serves as an introduction to NiMH modeling, and can be further extended to include ... Read More
MEMS scanning mirrors are a type of MEMS device that realizes optical path control by controlling mirror torsion through a microdriver. The torsion can be single axis or double axis. MEMS scanning mirrors are widely used in laser projection, laser radar, laser processing, and other ... Read More
In this tutorial, the acoustic radiation pattern from a small generic loudspeaker is analyzed using the boundary element method (BEM). The loudspeaker is located on a small table above the floor and at a given distance from a wall. The model is set up using the Pressure Acoustics, ... Read More
This tutorial demonstrates how to integrate multiple Lumped Battery models into the Electrical Circuit interface. Two batteries are connected in series. Each battery is protected by a shunt resistances that is activated if the battery state-of-charge reaches below a certain threshold ... Read More
A deceptively simple system of two species and two reactions, describing the autocatalytic conversion of a substance, is shown to display a surprisingly exotic behavior. Starting from a 0D CSTR description, a 2D reaction-diffusion problem is formulated showing rich patterns stemming from ... Read More
In this example, the deformation of a rubber boot seal connected to a rigid pipe is studied. As the pipe rotates and the seal deforms, the flanges of the seal self-intersect and it also come into contact with the pipe. Read More
This model demonstrates how to simulate the propagation of guided waves in a dielectric S-bent optical waveguide. The model demonstrates that the phase approximation, required by the Electromagnetic Waves, Beam Envelopes interface, can be numerically calculated by solving an additional ... Read More
This model demonstrates how to use the Polynomial Shell feature to increase the lowest Eigenfrequency of a shell by deforming its shape. Read More
This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The ... Read More
