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.
In this example, a heterogeneous NMC (Nickel-Manganese-Cobalt) electrode structure is generated from tomography data using a Model Method. Time-dependent discharge and electrochemical impedance spectroscopy (EIS) simulations are then made on the full 3D geometry. A solid mechanics ... Read More
This model demonstrates the simulation of the scattering of a plane wave of light by a gold nanosphere. The scattering is computed for the optical frequency range over which gold can be modeled as a material with negative complex-valued permittivity. The far-field pattern and losses are ... Read More
A capacitive pressure sensor is simulated. This model shows how to simulate the response of the pressure sensor to an applied pressure, and also how to analyze the effects of packing induced stresses on the sensor performance. Read More
This tutorial model of a two-hot-arm thermal actuator couples three different physics phenomena: electric current conduction, heat conduction with heat generation, and structural stresses and strains due to thermal expansion. The model exists in three versions: Joule Heating of a ... Read More
In COMSOL Multiphysics, you can import mesh and interpolation data created by other software for use in your simulations. You can also export data created in COMSOL Multiphysics to use in other COMSOL models and applications as well as other software. This document and accompanying ... Read More
This example simulates turbulent flow around a sports car traveling at a speed of 180 km/h using Large Eddy Simulations (LES). Read More
This example demonstrates how to model the temperature distribution in a battery pack during a 4C discharge. The pack is constructed by first coupling two cylindrical batteries in parallel. Six parallel-connected pairs are then connected in series to create the full pack. (This is also ... Read More
This model demonstrates the Lithium-Ion Battery interface for studying the discharge and charge of a lithium-ion battery for a given set of material properties. The geometry is in one dimension and the model is isothermal. Battery developers can use the model to investigate the influence ... Read More
This example demonstrates how to use the Electrostatic interface to calculate the surface electric field of a typical high-voltage insulator. It is shown that the inhomogeneity and the maximum of the surface electric field are greatly reduced with the installation of the grading rings. ... Read More
Alkaline water electrolysis is a well-established industrial process for producing hydrogen gas. In the cell, hydrogen gas is formed at the cathode whereas oxygen gas is formed at the anode. The electrolyte is an aqueous liquid, and when the evolved gases form bubbles, the effective ... Read More
