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.
Seawater intrusion is a critical issue in coastal regions, where it endangers both freshwater supplies and the overall quality of groundwater. This example showcases seawater intrusion in a coastal aquifer where a pumping well is located at some distance from the shoreline. The model ... Read More
Chain drives are used for transmitting power from one shaft to another, located at some distance. This example simulates the dynamics of a chain sprocket assembly in 2D. The geometry consists of a roller chain wrapped around two sprockets. Both chain links and sprockets are assumed to be ... Read More
An isothermal single particle model formulation for a lithium-ion battery is presented in this work. The single particle model is a simplification of the 1D formulation for a lithium-ion battery along with a few assumptions. The model is typically valid for low-medium current scenarios. ...

This example models an oil reservoir with two horizontal wells. The reservoir contains two phases, water and oil. Oil is recovered by injecting water through the bottom well, so the oil production rate and the water-oil production ratio over time are computed. Read More
An ultrasonic standing wave levitator, also called acoustic levitator, is a device used for levitating fluid and solid particles in an acoustic field. The standing acoustic waves exert an acoustic radiation force on the particles. The force is a second order effect and stems from a ... Read More
This is a benchmark model to test the numerical algorithms in the area of multibody dynamics. This model simulates the dynamic behavior of the slider crank mechanism. This mechanism goes through singular positions during its operation. The acceleration at a point is compared with the ... Read More
This model example shows how to model nonlinear propagation of a cylindrical wave using the Nonlinear Pressure Acoustics, Time Explicit physics interface available in Acoustics Module of COMSOL Multiphysics. The interface implements the system of nonlinear acoustic equations in the form ... Read More
The model is defined as a benchmark case in norm 15026:2007 annex A. The purpose of the model is to calculate the temperature and moisture profiles at different times after a change in the external conditions (temperature and relative humidity) inside a wall material (kind of concrete). ...

Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... Read More
This tutorial shows how to set up a 3D simulation of rubber injection molding. A phase field method is used to track the interface between the rubber and the displaced air. The rubber is modeled as shear-thinning inelastic non-Newtonian power law fluid with a fluid-consistency ... Read More
