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 model presents a study of a coaxial DC corona discharge in dry air at atmospheric pressure. The dimensions and operation conditions are similar to ones found in electrostatic precipitators with wire-to-plate configurations. The inner wire electrode has a 100-mm radius and ... Read More
This tutorial shows how to model tissue heating induced by focused ultrasound. First, the stationary acoustic field in the water and the tissue are modeled to obtain the acoustic intensity distribution in the tissue. The absorbed acoustic energy is then calculated and used as the heat ... Read More
In this tutorial model, different methods for modeling brittle damage are compared in a simple model of a uniaxially loaded bar. The localization of the deformation during fracture is studied using different discretization orders and regularization methods. Read More
This is the model of an occluded ear canal simulator (a generic 711 coupler). Besides certain details the geometry corresponds to the Brüel & Kjær Ear Simulator Type 4157. The real life couplers are used for simulating the acoustics of a standardized human ear canal and can be used ... Read More
The GEC cell was introduced by NIST in order to provide a standardized platform for experimental and modeling studies of discharges in different laboratories. The plasma is sustained via inductive heating. The Reference Cell operates as an inductively-coupled plasma in this model. This ... Read More
This tutorial models the cathodic protection of an oil rig structure during a time period of 15 years. As a result of the consumption of the sacrificial anodes, the protective capabilities system are reduced over time. The anode shape change in the model is defined by using the Level ... Read More
This example performs the analysis of a viscoelastic damper. The damper is intended for reduction of wind-induced and seismic vibrations in buildings and other tall structures. Read More
This tutorial models the acoustic behavior of a loudspeaker driver mounted in a bass reflex enclosure. The enclosure, sometimes called the cabinet, alters substantially the sensitivity and radiation characteristics of the loudspeaker and it is why it is usually considered part of the ... Read More
A Gaussian beam is launched into BK-7 optical glass. The material has an intensity-dependent refractive index. At the center of the beam, the refractive index is the largest. The induced refractive index profile counteracts diffraction and actually focuses the beam. Self-focusing is ... 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
